Size: 1-13/16" - 4-1/16"
Pressure: 2000psi - 15000psi
Features: Parallel expanding gate design creates positive mechanical seal across both seats, both upstream and downstream, with or without line pressure.
Non-rising stem permits valve installation in pressure drop
A double row roller thrust bearing on the stem makes operation easy, even under full pressure.
Upper and lower roller thrust bearings are used to minimize torque and are isolated from well-bore fluid.
