Shaft Versatility— This valve will meet your actuator needs with a choice of square, keyed, or splined shaft connections.
Excellent Shutoff Integrity—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.
Excellent Emissions 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. The seal of the ENVIRO-SEAL system can control emissions to below 100 ppm (parts per million).
Sour Service Capability— Trim and bolting materials are available for applications involving sour liquids and gases. These constructions comply with NACE MR0175-2002, MR0103, and MR0175 / ISO 15156.
High-Temperature/Cryogenic Capabilities— Optional valve constructions allow this valve to meet both high-temperature and cryogenic applications.
Easy Installation—The valve body self-centers on the line flange bolts as a fast, accurate means of centering the valve in the pipeline.
Reliable Flange Gasketing Surface—Seal retainer screws are located so there is no interference with the sealing function of either flat sheet or spiral wound line flange gaskets.
True Bidirectional Shutoff Performance—A feature of the valve design is that the torque necessary to open and close the valve is the same regardless of the direction in which the differential pressure is applied.
Ease of Maintenance—Interchangeability of all parts, including shafts and discs, simplifies service and reduces maintenance costs.
