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.
