Product Name:

HP Ball Valve

Product Short Description:

Classic design, compact and reliable on/off valve

Features and Applications:

General high purity gas piping (high pressure/low pressure applications)

Directional handle to indicate port position

Precision forged valve body with square profile design

Top-loading design allows valve to be adjusted in-line

One-piece spherical stem ensures stem to orifice alignment

No dead space, easy to clean and purge, allows bi-directional flow

Panel Mount

With Panel Mount Nut


Each SCT ball valve is designed to be used in the fully open or fully closed position

Valves that have not been used for a period of time will have a higher initial actuation torque

Packing adjustment may be required to prevent leakage during the valve's life cycle.


Important Information:

Every valve is factory tested with nitrogen at 1000 psig (69 bar). If less than 1000 psig (69 bar), the valve is tested at its rated pressure.

Valves that are used at pressures higher than the test pressure must have the valve packing readjusted.

Instrumented ball valves exposed to dynamic temperature conditions prior to installation may lose their initial packing load. Packing adjustment may be required.
