Structure and Application of Double Disc Wedge Gate Valve
Double disc wedge gate valves are a type of gate valve that use two parallel discs to control the flow of fluids through a pipeline. These valves are commonly used in high-pressure and high-temperature applications, as well as in applications that require tight shutoff.
The double disc design valves ensures that the valve provides a bi-directional seal, allowing the flow to be controlled from either direction. This design also reduces the operating torque required to open and close the valve, making it more efficient and easier to operate.
The body of the double disc wedge gate valve is typically made of cast or ductile iron, while the discs are made of stainless steel or other alloys. The type of van cổng is typically operated using a handwheel or gear operator, but can also be automated using an electric or pneumatic actuator.
Farpro double disc wedge gate valves are commonly used in a variety of industries, bao gồm cả dầu khí, hóa dầu, sản xuất điện, and water and wastewater treatment. They are also used in fire protection systems, irrigation systems, and other applications that require reliable and efficient flow control.
