V96 Series Rising Stem Plug Valves
Pressure Ratings up to 6,000 psig (413 bar)
Features
Technical Information
Flow Coefficiency at 100° F (37 °C)
Testing
Materials of Construction
•
Bi-directional flow control.
•
Straight-through orifice hence roddable for easy cleaning.
•
Acetal seat standard, optional PEEK and PFA.
•
Non-rotating Stem Tip for positive sealing and maximum soft seat life.
•
Internal bonnet O-ring protects threads from external contamination.
•
Isolated threads located above bonnet O-ring prevents media contamination
and thread lubricant washout.
Pressure-Temperature
Ratings are based on standard stem tip of FKM O-ring and PTFE backup rings.

Every valve is factory tested with the nitrogen gas @ 1,000 psig (68 bar) for leakage at the seat to a maximum allowable leak rate of
0.1 SCCM. Stem seals are tested to a requirement of no detectable leakage using a liquid leak detector.
