Features
- This valve will meet your actuator needs with a choice of splined, square, or keyed shaft connections.
- 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.
- 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.
- Trim and bolting materials are available for applications involving sour liquids and gases.
- 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.
- The torque necessary to open and close the valves is the same, regardless of the direction in which the differential pressure is applied.
