Double Disk Parallel Gas Gate Valves

A double-disc gate valve is also known as a parallel double-disc gate valve. A double-disc gate valve is a type of gate valve which has two discs and two seats. The disc in a double-disc gate valve are used to open or close fluid flow. The two-disc expand from each other when the valve is working. Double disc gate valve manufacturers design these valves for use in on and off fluid flow applications. These valves are not meant for use in throttling applications. Double disc gate valves have tight seals which ensure zero fluid leakage unless there is mechanical damage to parts of the valve. Double disc gate valves are operated manually using the valve handwheel or through actuators such as pneumatic, electric and hydraulic actuators. Double disc gate valves have two disc seals. The sealing is enhanced by combining internal fluid pressure and spring force. A floating seat is used to relieve pressure automatically when middle section of the valve is under pressure.
