Gate valve (gate valve) is a gate, the movement direction of the gate is perpendicular to the direction of the fluid, and the gate valve can only be fully open and closed, and cannot be regulated and throttling.The gate has two sealing covers, the most commonly used mode gate valve two sealing surface to form wedge, wedge Angle valve.
The parameters are different, usually 50, and the medium temperature is 425 when the temperature is not high.The gate of a wedge gate can be made into a whole, called a steel ram.It can also be made to produce a small amount of deformation of the gate, to improve its technology, to make up the Angle of the sealing surface in the processing of the deviation, this gate is called flexible gate.
