Features

The pressure-assisted seal design provides tight shutoff against the full pressure rating of the specified valve.

The anti-blowout gland fits securely over the valve shaft, which has been turned down to form a circumferential shoulder that contacts the anti-blowout gland.

A splined end connection on the drive shaft allows lever clamping by most EO rotary actuators.

Optional keyed shaft is ideal for on/off applications and allows actuator selection flexibility.

The optional ENVIRO-SEAL™ packing system is designed with very smooth stem surfaces and live-loading provides improved sealing, guiding, and loading force transmission.

The valve body self-centers on the line flange bolts as a fast, accurate means of centering the valve in the pipeline.

Seal retainer screws are located so there is no interference with the sealing function of either flat sheet or spiral-wound line flange gaskets.
