FEATURES

1.Developed as a valve/actuator packing with a double D drive shaft to allow easy, direct mounting to a rack and pinion actuator, eliminating the need for external coupling systems.

2.Concentric rotation ensures that the valve disk remains in the closed position, even in the event of line pressure surges or actuator failure.

3.The torque necessary to open and close the valve is the same, regardless of the direction in which the differential pressure is applied.

4.Interchangeability of all parts, including shafts and disks, simplifies service and reduces maintenance costs.

5.Seal retainer screws are located so there is no interference with the sealing function of either flat sheet or spiral-wound line flange gaskets.
