THE POSITIVE CHOKE VALVE
The positive choke valve is employed on Christmas trees and wellheads and designed for flow control. In order to control flow rate, the positive choke valve uses flow beans in different orifice diameters that can be changed to adjust the effective area available for the flow.
Main technical parameters
Rated pressure: 2000-15000psi
Working temperature: P U
Working medium ：petroleum & natural gas.
Orifice diameters of flow beans: 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12
All pressure-containing parts are made from alloy steels for enough tensile strength in order to ensure the safety and reliability at rated working pressure.
Choke beans are made from hard alloys for good wear and erosion resistance.
