Product overview
1. Gate valve opening and closing member is the gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully open and fully closed, can not be used for regulating and throttling. 2. gate valve gate with the stem together for linear movement, called the lifting stem gate valve (also called open stem gate valve). Usually in the lifting rod on the trapezoidal thread, through the valve end of the nut and the valve body on the guide groove, the rotary movement into a straight 3 line movement, that is, the operating torque into the operating thrust.

(1) the fluid resistance is small, the sealing surface by the medium of the brush and erosion;
(2) open and close less effort;
(3) the medium flow direction is not restricted, do not disturb the flow, do not reduce the pressure;
(4) simple shape, short structure length, manufacturing process is good, wide range of applications. -
