Outer cage type choke valve
The unique integrated cage design technology increases the inner annular space and reduces erosion, making the valve core corrosion low and controllable flow large. The metal main seal between the valve body and the valve cover and the PTFE multi-stage lip spring auxiliary seal on the valve stem ensure the sealing performance of the choke valve. The indicator with 64 grid visible position on the top is convenient for understanding the flow rate. The cage structure can reduce the vibration and noise of the equipment and has good stability. Manual, hydraulic, pneumatic or electric and other drive forms, convenient for customers to choose. The equipment maintenance is simple and the manufacturing cost is low.
