Choose from square, keyed, or splined shaft connections.
The pressure-assisted seal design provides tight shutoff.
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 of either flat sheet or spiral-wound line flange gaskets.
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.
Interchangeability of all parts, including shafts and disks, simplifies service and reduces maintenance costs.
