The YDK electric actuated butterfly valve<\/strong> is an automatic open\/close butterfly valve that eliminates manual operation. Like other isolation valves, it has two states: ON (fully open) and OFF (fully closed). It is therefore not suitable for throttling or regulating fluid flow.<\/p>\n

Electric actuated butterfly valves are commonly used in automated piping systems such as water supply and drainage, fire protection, HVAC, and industrial projects.<\/p>\n

Introducing the YDK Electric Actuated Butterfly Valve<\/h2>\n

The YDK electric actuated butterfly valve is made of durable GGG50 ductile iron, coated with epoxy paint for corrosion resistance in harsh environments. Its standout feature is the stamped CF8\/SS304 stainless steel disc, which offers excellent corrosion resistance and a smooth surface that minimizes flow resistance. The EPDM seat has good elasticity, ensuring a tight seal at working pressures of PN10 – PN16.<\/p>\n

Acting as the “brain” of the valve, the electric actuator converts electrical energy into powerful torque, rotating the disc through 0\u00ba to 90\u00ba. The actuator housing is made of high-pressure die-cast aluminum alloy and designed to the IP67 standard for water and dust resistance, allowing stable operation outdoors or in high-humidity conditions. The actuator also features a built-in hex key \/ auxiliary handwheel override, allowing technicians to open and close the valve manually during emergency power outages.<\/p>\n

The YDK electric actuated butterfly valve runs on an AC220V power supply with 35W power consumption, and integrates flexibly into most central control panels and automated PLC systems.<\/p>\n

Working Principle of the YDK Electric Actuated Butterfly Valve<\/h2>\n

Transmission mechanism inside the electric actuator<\/h3>\n

Inside the actuator is a small AC electric motor. When it receives an electrical signal from the control panel or a switch, the motor rotates and drives a reduction gearbox that raises the torque to a sufficiently high level (up to 150 Nm) while lowering the rotation speed to a suitable level. The motion is then transmitted to the stem of the butterfly valve<\/a> below, rotating the disc 90\u00ba to close or open.<\/p>\n

ON\/OFF mechanism<\/h3>\n

Unlike modulating actuators, which can stop at any angle according to the signal, the ON\/OFF actuator of the YDK electric actuated butterfly valve operates in only two fixed states: fully closed or fully open. Inside the actuator, limit switches are set at the 0\u00ba and 90\u00ba positions. When the disc reaches the fully closed or fully open position, the limit switch contacts its stop and cuts power to the motor, halting movement at the right moment. This prevents the motor from continuing to run, which could cause overload or damage the disc and seat through excess torque.<\/p>\n

Control signal<\/h3>\n

The actuator receives open or close commands through a simple electrical signal, usually from a local toggle switch, a push button on the control panel, or a relay contact from an automation system (PLC, water level sensor, fire alarm system). On an open command, the motor turns in one direction to bring the disc to the open position. On a close command, the motor reverses to bring the disc to the closed position.<\/p>\n

Why Do Contractors Trust the YDK Electric Actuated Butterfly Valve?<\/h2>\n

Compared with solenoid valves or ordinary manual valves, the YDK electric actuated butterfly valve offers several clear advantages:<\/p>\n
