FEATURES

1.This valve will meet your actuator needs with a choice of splined, square, or keyed shaft connections.

2.The pressure-assisted seal design provides tight shutoff and permits the use of smaller, less expensive actuators in applications requiring full ASME B16.34 shutoff capabilities.

3.The optional ENVIRO-SEAL™ packing systems are designed with very smooth shaft surfaces and live-loading to provide improved sealing, guiding, and loading force transmission.

4.Trim and bolting materials are available for applications involving sour liquids and gases.

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

6.Seal retainer screws are located so there is no interference with the sealing function.
