        Economical Tight Shutoff—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 Shutoff Integrity—Concentric rotation helps to ensure that the valve disc remains in the closed position in spite of line pressure surges or actuator failure.

        True Bi-directional Shutoff Performance— Valve design helps to ensure that the torque necessary to open and close the valve is the same regardless of the direction in which the differential pressure is applied.

        Safety—Shaft blowout protection is designed into the Type A31A 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.

        Improved Environmental Capabilities — The optional ENVIRO-SEAL packing system is designed with improved sealing, guiding, and loading force transmission. The ENVIRO-SEAL packing system can control emissions to below the EPA (Environmental Protection Agency) limit of 500 ppm (parts per million) for valves.
