Structural Characteristics and Manufacturing Materials of YDK Rising Stem Gate Valve<\/h2>\n
Unlike non-rising stem valve series, the YDK KRX-16 gate valve series is designed with a rising stem where the threaded stem lies outside the valve body. This design makes maintenance and servicing more convenient while allowing easy visual inspection of the valve’s OPEN\/CLOSED status.<\/p>\n
The YDK KRX-16 rising stem gate valve consists of 5 main parts:<\/p>\n
\n
\n
Body and Bonnet:<\/b> Cast from GGG50 ductile iron, providing better mechanical impact resistance and anti-cracking properties than gray cast iron. The inner and outer surfaces are coated with Epoxy resin to prevent electrochemical corrosion in underground environments or high-humidity conditions.<\/p>\n<\/li>\n
\n
Valve Stem:<\/b> Made of Grade 420 Stainless Steel with high surface hardness, capable of withstanding large torsional forces without warping, and reducing thread wear during continuous open\/close operations. The control thread section is located outside the valve body, making it easy to grease for maintenance and minimizing rust or thread jamming during operation.<\/p>\n<\/li>\n
\n
Valve Disc (Wedge):<\/b> GGG50 ductile iron core fully encapsulated in EPDM rubber. The resilient rubber encapsulation design ensures Class A sealing performance (ISO 5208) and prevents jamming when small debris enters.<\/p>\n<\/li>\n
\n
**Sealing Gasket & Bolts:<\/b> Heat-resistant EPDM gasket; Body-bonnet connecting bolts use Grade 8.8 carbon steel.<\/p>\n<\/li>\n<\/ul>\n**

Practical Applications of YDK Rising Stem Gate Valve<\/h2>\n
The YDK KRX-16 rising stem valve series is a specialized flow control solution for items requiring high safety standards, such as:<\/p>\n
\n
\n
Fire Fighting \/ Protection Pump Stations (PCCC):<\/b> Mandatory installation on the suction\/discharge pipes of main pump sets or branch line shut-off valves according to TCVN 3890 \/ QCVN 06 standards. Thanks to the raised valve stem, fire fighting forces or building engineers can immediately recognize whether the valve is OPEN or CLOSED without test operation.<\/p>\n<\/li>\n
\n
Clean Water Treatment Stations & Water Supply Infrastructure:<\/b> Since the gate valve opens completely clear of the pipe when fully open\u2014without obstructing or reducing water thrust\u2014it is highly suitable for installation in technical pits on main water pipelines as a shut-off valve.<\/p>\n<\/li>\n
\n
**HVAC \/ Central Chiller Systems:<\/b> Used as shut-off valves on condensate water pipes and chilled water distribution lines for floors.<\/p>\n<\/li>\n<\/ul>\n**
$\"\u01af\u0301ng$
YDK rising stem gate valves are used in many fire protection, water treatment, and high-rise building projects..<\/figcaption><\/figure>\n
Installation and Maintenance Notes for Rising Stem Gate Valves<\/h2>\n
The entire installation process for rising stem gate valves must comply with M&E Piping Installation Standards:<\/p>\n
\n
\n
No Dead Space:<\/b> Because the valve stem rises high when opening, clear space must be left above the handwheel equal to at least 1.5 x DN to avoid scraping against floor soffits, plaster ceilings, or cable trays.<\/p>\n<\/li>\n
\n
Optimal Installation Direction:<\/b> Vertical installation with the stem perpendicular to the ground is preferred. If horizontal installation is mandatory, a valve assembly support stand must be provided for sizes DN150 and above to prevent pipe sagging and flange eccentricity.<\/p>\n<\/li>\n
\n
Rising Stem Maintenance:<\/b> The Stainless Steel 420 threaded stem exposed to the environment easily attracts dirt and construction sand. A periodic lubrication schedule of once every 6 months is necessary for smooth handwheel operation and to prevent thread scratching.<\/p>\n<\/li>\n
\n
**Bolt Tightening:<\/b> Tighten diagonally and symmetrically according to standard torque for PN10\/16 flanges to avoid flange warping that could tear the rubber gasket.<\/p>\n<\/li>\n<\/ul>\n**

Practical Applications of YDK Rising Stem Gate Valve<\/h2>\n
The YDK KRX-16 rising stem valve series is a specialized flow control solution for items requiring high safety standards, such as:<\/p>\n
\n
\n
Fire Fighting \/ Protection Pump Stations (PCCC):<\/b> Mandatory installation on the suction\/discharge pipes of main pump sets or branch line shut-off valves according to TCVN 3890 \/ QCVN 06 standards. Thanks to the raised valve stem, fire fighting forces or building engineers can immediately recognize whether the valve is OPEN or CLOSED without test operation.<\/p>\n<\/li>\n
\n
Clean Water Treatment Stations & Water Supply Infrastructure:<\/b> Since the gate valve opens completely clear of the pipe when fully open\u2014without obstructing or reducing water thrust\u2014it is highly suitable for installation in technical pits on main water pipelines as a shut-off valve.<\/p>\n<\/li>\n
\n
**HVAC \/ Central Chiller Systems:<\/b> Used as shut-off valves on condensate water pipes and chilled water distribution lines for floors.<\/p>\n<\/li>\n<\/ul>\n**
$\"\u01af\u0301ng$
YDK rising stem gate valves are used in many fire protection, water treatment, and high-rise building projects..<\/figcaption><\/figure>\n
Installation and Maintenance Notes for Rising Stem Gate Valves<\/h2>\n
The entire installation process for rising stem gate valves must comply with M&E Piping Installation Standards:<\/p>\n
\n
\n
No Dead Space:<\/b> Because the valve stem rises high when opening, clear space must be left above the handwheel equal to at least 1.5 x DN to avoid scraping against floor soffits, plaster ceilings, or cable trays.<\/p>\n<\/li>\n
\n
Optimal Installation Direction:<\/b> Vertical installation with the stem perpendicular to the ground is preferred. If horizontal installation is mandatory, a valve assembly support stand must be provided for sizes DN150 and above to prevent pipe sagging and flange eccentricity.<\/p>\n<\/li>\n
\n
Rising Stem Maintenance:<\/b> The Stainless Steel 420 threaded stem exposed to the environment easily attracts dirt and construction sand. A periodic lubrication schedule of once every 6 months is necessary for smooth handwheel operation and to prevent thread scratching.<\/p>\n<\/li>\n
\n
**Bolt Tightening:<\/b> Tighten diagonally and symmetrically according to standard torque for PN10\/16 flanges to avoid flange warping that could tear the rubber gasket.<\/p>\n<\/li>\n<\/ul>\n**

It is specialized for water supply and drainage infrastructure, fire protection pump stations, wastewater treatment, and technical pipelines in high-rise buildings and apartments. The rising stem design allows easy visual identification of the valve’s OPEN\/CLOSED status from a distance without needing additional support devices. Structural Characteristics and Manufacturing Materials of YDK Rising Stem Gate Valve Unlike non-rising stem valve series, the YDK KRX-16 gate valve series is designed with a rising stem where the threaded stem lies outside the valve body. This design makes maintenance and servicing more convenient while allowing easy visual inspection of the valve’s OPEN\/CLOSED status. The YDK KRX-16 rising stem gate valve consists of 5 main parts: Body and Bonnet: Cast from GGG50 ductile iron, providing better mechanical impact resistance and anti-cracking properties than gray cast iron. The inner and outer surfaces are coated with Epoxy resin to prevent electrochemical corrosion in underground environments or high-humidity conditions. Valve Stem: Made of Grade 420 Stainless Steel with high surface hardness, capable of withstanding large torsional forces without warping, and reducing thread wear during continuous open\/close operations. The control thread section is located outside the valve body, making it easy to grease for maintenance and minimizing rust or thread jamming during operation. Valve Disc (Wedge): GGG50 ductile iron core fully encapsulated in EPDM rubber. The resilient rubber encapsulation design ensures Class A sealing performance (ISO 5208) and prevents jamming when small debris enters. Sealing Gasket & Bolts: Heat-resistant EPDM gasket; Body-bonnet connecting bolts use Grade 8.8 carbon steel.

Thanks to the raised valve stem, fire fighting forces or building engineers can immediately recognize whether the valve is OPEN or CLOSED without test operation.<\/p>\n<\/li>\n \n Clean Water Treatment Stations & Water Supply Infrastructure:<\/b> Since the gate valve opens completely clear of the pipe when fully open\u2014without obstructing or reducing water thrust\u2014it is highly suitable for installation in technical pits on main water pipelines as a shut-off valve.<\/p>\n<\/li>\n \n HVAC \/ Central Chiller Systems:<\/b> Used as shut-off valves on condensate water pipes and chilled water distribution lines for floors.<\/p>\n<\/li>\n<\/ul>\n $\"\u01af\u0301ng$ YDK rising stem gate valves are used in many fire protection, water treatment, and high-rise building projects..<\/figcaption><\/figure>\n Installation and Maintenance Notes for Rising Stem Gate Valves<\/h2>\n The entire installation process for rising stem gate valves must comply with M&E Piping Installation Standards:<\/p>\n \n \n No Dead Space:<\/b> Because the valve stem rises high when opening, clear space must be left above the handwheel equal to at least 1.5 x DN to avoid scraping against floor soffits, plaster ceilings, or cable trays.<\/p>\n<\/li>\n \n Optimal Installation Direction:<\/b> Vertical installation with the stem perpendicular to the ground is preferred. If horizontal installation is mandatory, a valve assembly support stand must be provided for sizes DN150 and above to prevent pipe sagging and flange eccentricity.<\/p>\n<\/li>\n \n Rising Stem Maintenance:<\/b> The Stainless Steel 420 threaded stem exposed to the environment easily attracts dirt and construction sand. A periodic lubrication schedule of once every 6 months is necessary for smooth handwheel operation and to prevent thread scratching.<\/p>\n<\/li>\n \n Bolt Tightening:<\/b> Tighten diagonally and symmetrically according to standard torque for PN10\/16 flanges to avoid flange warping that could tear the rubber gasket.<\/p>\n<\/li>\n<\/ul>\n See more:<\/b><\/p>\n <span data-mce-type=\"bookmark\" style=\"display: inline-block; width: 0px; overflow: hidden; line-height: 0;\" class=\"mce_SELRES_start\">\ufeff<\/span><\/iframe><\/p>\n<h2 style=\"text-align: justify;\" data-path-to-node=\"24\">Legal Documentation and Warranty Policy<\/h2>\n<p style=\"text-align: justify;\" data-path-to-node=\"25\">An Ph\u00fa Th\u00e0nh provides a comprehensive turnkey YDK rising stem gate valve solution for M&E designers, MEP contractors, fire protection construction units, etc.:<\/p>\n<ul data-path-to-node=\"26\">\n<li style=\"text-align: justify;\">\n<p data-path-to-node=\"26,0,0\">100% Genuine YDK Products.<\/p>\n<\/li>\n<li style=\"text-align: justify;\">\n<p data-path-to-node=\"26,1,0\">Complete inspection\/acceptance documentation: CO, CQ, Packing List, VAT Invoice, Catalogue, etc.<\/p>\n<\/li>\n<li style=\"text-align: justify;\">\n<p data-path-to-node=\"26,2,0\">Dedicated Consultation: Detailed technical support on products, flange connection standards, etc.<\/p>\n<\/li>\n<li>\n<p style=\"text-align: justify;\" data-path-to-node=\"26,3,0\">Project Policy: Volume discounts based on order size, 12-month genuine warranty, nationwide delivery support.<\/p>\n<\/li>\n<\/ul>\n<figure id=\"attachment_14726\" aria-describedby=\"caption-attachment-14726\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-14726 size-full\" src=\"https:\/\/anphuthanhvalve.com\/wp-content\/uploads\/2026\/09\/van-cong-ty-noi-YDK-4.jpg\" alt=\"An Phu\u0301 Tha\u0300nh chuy\u00ean cung c\u00e2\u0301p Van c\u00f4ng nghi\u00ea\u0323p, phu\u0323 ki\u00ea\u0323n \u0111\u01b0\u01a1\u0300ng \u00f4\u0301ng\" width=\"800\" height=\"500\" srcset=\"https:\/\/anphuthanhvalve.com\/wp-content\/uploads\/2026\/09\/van-cong-ty-noi-YDK-4.jpg 800w, https:\/\/anphuthanhvalve.com\/wp-content\/uploads\/2026\/09\/van-cong-ty-noi-YDK-4-300x188.jpg 300w, https:\/\/anphuthanhvalve.com\/wp-content\/uploads\/2026\/09\/van-cong-ty-noi-YDK-4-768x480.jpg 768w, https:\/\/anphuthanhvalve.com\/wp-content\/uploads\/2026\/09\/van-cong-ty-noi-YDK-4-600x375.jpg 600w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption id=\"caption-attachment-14726\" class=\"wp-caption-text\">An Ph\u00fa Th\u00e0nh provides turnkey YDK rising stem gate valve solutions<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">If you need price quotes or technical consultation regarding YDK rising stem gate valves, please contact <a href=\"https:\/\/anphuthanhvalve.com\/en\/\">An Ph\u00fa Th\u00e0nh<\/a> via Hotline\/Zalo OA <a href=\"https:\/\/zalo.me\/657438188627359243\" target=\"_blank\" rel=\"noopener\">0946 729 913<\/a>.

It is specialized for water supply and drainage infrastructure, fire protection pump stations, wastewater treatment, and technical pipelines in high-rise buildings and apartments. The rising stem design allows easy visual identification of the valve’s OPEN\/CLOSED status from a distance without needing additional support devices. Structural Characteristics and Manufacturing Materials of YDK Rising Stem Gate Valve Unlike non-rising stem valve series, the YDK KRX-16 gate valve series is designed with a rising stem where the threaded stem lies outside the valve body. This design makes maintenance and servicing more convenient while allowing easy visual inspection of the valve’s OPEN\/CLOSED status. The YDK KRX-16 rising stem gate valve consists of 5 main parts: Body and Bonnet: Cast from GGG50 ductile iron, providing better mechanical impact resistance and anti-cracking properties than gray cast iron. The inner and outer surfaces are coated with Epoxy resin to prevent electrochemical corrosion in underground environments or high-humidity conditions. Valve Stem: Made of Grade 420 Stainless Steel with high surface hardness, capable of withstanding large torsional forces without warping, and reducing thread wear during continuous open\/close operations. The control thread section is located outside the valve body, making it easy to grease for maintenance and minimizing rust or thread jamming during operation. Valve Disc (Wedge): GGG50 ductile iron core fully encapsulated in EPDM rubber. The resilient rubber encapsulation design ensures Class A sealing performance (ISO 5208) and prevents jamming when small debris enters. Sealing Gasket & Bolts: Heat-resistant EPDM gasket; Body-bonnet connecting bolts use Grade 8.8 carbon steel.
