Hydraulic Check Valve: Construction, Features, and Best Price Quote

Hydraulic check valves are a type of valve receiving a great deal of attention today and are widely used in many fields. So, what is the construction and operating principle of this equipment? How can you purchase genuine products at the best prices on the market? Let’s find out in the article below.

What is a Hydraulic Check Valve?

A check valve is a very familiar device in fluid transportation systems. The characteristic of this type of valve is its ability to open and close completely automatically under the pressure of the flowing fluid, while only allowing the fluid to flow in one direction and preventing reverse flow.

The purpose of this type of valve is to completely prevent reverse water flow, which can cause fluid loss, while also preventing water hammer that may damage pipelines and surrounding equipment.

A hydraulic check valve is a type of check valve designed primarily for use in hydraulic systems. Since its operating environment typically involves ordinary liquids or special fluids such as gasoline, oil, and chemicals, these valves are commonly manufactured from highly durable materials such as steel and stainless steel.

This type of valve features a relatively compact design with a robust cast body, capable of withstanding high pressure and high temperatures while providing good resistance to corrosion and oxidation. The pressure resistance can reach up to 300 bar, while the flow rate through the valve can reach up to 650 liters/minute.

Today, hydraulic check valves are used in many fields, such as hydraulic pump systems, fire protection systems, water supply and drainage systems, oil transfer systems, oil storage systems, and more.

Construction of a Hydraulic Check Valve

For this equipment to operate effectively and provide high durability, it is constructed from the following components:

• Valve Body: Cast from high-hardness materials with substantial thickness and excellent resistance, such as stainless steel and steel. The body is resistant to cracking, breakage, and vibration during operation. Internal threads are designed on the valve body for easy connection to pipelines.
• Valve Disc: Also known as the valve closure, it is designed to fit the valve’s nominal diameter and functions to open and close to prevent or allow fluid to pass through the valve.
• Spring: Usually manufactured from stainless steel, the spring features a helical design with high elasticity and is connected to the valve disc. Its elasticity causes the valve to open or close.
• Valve Seat: Installed inside the valve body, it functions as a fixed support for the valve disc.

Operating Principle of a Hydraulic Check Valve

The operating principle of a hydraulic check valve is similar to that of other types of check valves. It is designed to open and close automatically under the force of the flowing fluid.

Under normal conditions, when there is no fluid flowing through the system, the valve remains closed. When a quantity of liquid is pumped into the pipeline, the strong pressure of the flow acts on the valve disc.

The spring connected to the valve disc is compressed backward. As the spring is compressed, it causes the valve disc to move away from its original position, creating an opening that allows fluid to pass through without obstruction.

When the fluid flow stops, the spring is no longer subjected to flow pressure and automatically returns to its original position, pushing the valve disc back and completely closing the valve opening. At this point, all fluid that has entered the system is blocked inside and cannot flow backward.
