The structure of double disc gate valve
Casting material: WCB, WB36, WCC, WC 1, WC 6, WC 9, C12A
Forging material: A105, WB36, F22, F91, F92
Construction method: prefabrication (welding), casting
Application of double disc gate valve
Conditions of use: high pressure, high temperature, low temperature, wear, corrosion, high viscosity, vacuum
Fluid types: liquids, liquids containing solid particles – slurries, gases, powders and pulverulent media, high viscosity fluids, fine chemicals, plastics and polymers, general chemicals, petrochemicals
The double-disc gate valve, also known as the parallel double-disc gate valve, is a gate valve different from the wedge-shaped gate valve. It has two built-in discs, and the sealing is realized by the two discs, and the two discs expand each other during operation. If the expansion power is higher, the sealing performance is better. Valves can be driven by handwheels, electric actuators and pneumatic actuators.
