Technical Advantages
By adjusting the handwheel, the valve stem drives the valve needle to move up and down, so that the gap between the valve needle and the valve seat can be changed, as a result, the passage area can also be changed to control the flow rate and pressure of flowing media such as petroleum, natural gas, mud and so on in the access road.
