High Pressure Angle Needle Choke Valve Size 4-1/16"

Product Introduction

The choke valve, a main Description of Christmas tree, is design to control production rate of the oil well, with working pressure up to 10000psi. Choke valves can be classified as follows: Adjustable choke valves and positive choke valves.

By rotating hand wheel to drive the stem, the adjustable choke valve is designed to adjust the effective area available for the flow to accomplish control of production rate. The positive choke valve is design to accomplish control of production rate by changing flow beans.

The hydraulic choke valve is employed on manifolds and other assemblies and designed for flow control. In order to control flow rate, the hydraulic choke valve uses the valve core which can be lifed and lowered to adjust the effective area available.
