API 6A Expanding Gate Valve

The Expanding Gate Valve is designed with expanding style gate which can produce a high sealing force against both the upstream and downstream seats simultaneously as the handwheel is tightened. The available working pressure is from 2000 to 5000psi and size from 2-1/16" through 7-1/16". These valves meet or exceed the requirements of API standard, and they are used in a variety of wellhead and distribution applications.

Features & Benefits

Non-rising stem design minimizes the valve installation and operation space.
Expanding gate design provides a positive mechanical seal across seats, with or without line pressure, which ensures low pressure sealing.
Upper and lower roller thrust bearings are isolated from well fluid that minimizes operating torque. Low running stress enhances life of the gate-to-seat interface.
