Structural features: forged steel gate valve body cap connection design in three forms.The first is the body of forged steel gate valve bolted cover,designed by the connection form of the valve, the valve body and valve cover bolt connection, PLUG VALVESspiral wound gasket seal,easy maintenance is the advantage of this kind.The second is the body of solder connections forged steel valve cover, according to the design of this connection in the form of valve,the valve body and seal welded bonnet, Check Valvesthe advantage of this kind is no external leakage. The third is self-tight pressure forged steel gate valve cover, according to the design of this connection in the form of valve, the valve body and bonnet connection with screw mosquito, pressure from the seal ring seal, Balance Valves the greater of the internal pressure, the better the sealing performance is the advantage of this kind.
Fluid resistance is small, the sealing surface distressed by the brush of medium is small.Opening and closing more effort.The flow direction of medium is unrestricted, not overfall and not reduce the pressure.Simple shape, length of the structure is short, manufacturing process is good and in a wide scope of application.
