Pressure Gauge Needle Valve

Pressure Gauge Needle Valve

Introduction:

Pressure gauge needle valve is a type of stop valve, mainly used for pressure gauge pipe, because often connected with the pressure gauge, so also called pressure gauge stop valve. Pressure gauge needle valve is a good stop valve, mainly used for fluid pipeline cut off, open, change the flow of the medium function, the medium into the pressure gauge control, normally open form.

Application:

Pressure gauge valve is widely used in oil, gas, steam nitrogen hydrogen mixed medium pipeline, for testing the pressure of the closing device, it has a strong connection, good sealing performance, and has the characteristics of blowdown performance.

Working Principle:

When rotating the hand wheel clockwise, rotate the stem through the thread to make the needle valve spool slowly pressed to the end face of the valve seat, so that it is pressed tightly and sealed to achieve the closing function; When turning the hand wheel counterclockwise, the valve core slowly principles the seat, to achieve the purpose of opening.
