A Double Disc Gate Valve Manufacturer in USA is also known as a parallel double-disc gate valve. A double-disc gate valve is a type of gate valve that has two discs and two seats. The disc in a double-disc gate valve is 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 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.

Working
A Double Disc Gate Valve Manufacturer in USA is a kind of ceramic gate valve. Therefore, its structure and working principle are consistent with the gate valve, and its opening and closing body (valve plate) is driven by the valve stem to lift the sealing surface of the valve seat, which can connect or cut off the channel of the fluid.
With the help of the external power provided by the cylinder or handwheel, the valve stem drives the valve plate to move up and down to realize the opening and closing of the valve, and the preload of the spring set between the double gate plate is closely in contact with the valve plate and the valve seat during the valve opening and closing process to achieve sealing.
