Lockable Brass Gate Valve
Apr 17, 2018

The gate of the gate valve makes linear movement with the valve stem. It is called the lifting rod gate valve, also called the stem valve. Trapezoidal threads are usually provided on the lifting rods. The nut on the top of the valve and the guide groove on the valve body convert the rotation into a linear motion, that is, the operating torque becomes the operating thrust. When the valve is opened, when the lifting height of the gate is equal to 1:1 of the valve diameter, the channel of the fluid is completely open, but this position cannot be monitored during operation. In actual use, the vertex of the valve stem is used as a mark, that is, a position that does not move, as its fully open position.
