PVI ball valves have very low operating torques and a range of seat materials providing excellent process environmental compatibility. Our seats offer wide process compatibility while maintaining a positive sealing across the entire operating range. This high level of seat integrity allows both vacuum and high pressure services from one valve. Recommended for use in Oil, Gas, Petrochemical and general duty applications where reliable long term performance is essential. Stopper for ¼ turn shut-off is standard on all pressure ranges and sizes.
PVI ball valves are subjected to three pressure tests:
[a] Hydrostatic test at 1.5 times working pressure
[b] Low pressure pneumatic test at150 PSI (15 bar)
[c] Shell test to 1.5 times working pressure.

General Purpose Ball Valves : PVI's general purpose ball valves are an economical solution for reliable shut-off and isolation of in-process instruments. Ball valves are available in Stainless Steel, CS A105, Other Alloys, Brass, etc and are rated to 3,000 psi. Our general purpose valves are ideal for instrumentation systems requiring leak-free quarter-turn isolation of pressure and differential pressure instruments.
3-Piece Bolted Ball Valves : PVI’s 3-piece Bolted ball valves are offered with standard Reinforced-PTFE seats and seals and are NACE compliant. These valves feature stainless steel construction and provide reliable shut-off in high-demand processes. The valves are rated to 6,000 psi and are ideal in applications where ease of valve maintenance is important. 3-Piece valves are designed and manufactured with safety, security and replace ability in mind.
Panel Mounting Ball Valves : PVI’s Panel Mount Series ball valves are available in stainless steel and feature a live-loaded packing system to reduce the need for packing adjustments and improve thermal cycle performance. This 6,000 psi rated valve has a low dead space design, ideal for analytical systems or any application in which contamination is unacceptable.
Stainless Steel 10K Ball Valves : PVI’s stainless steel 10K ball valves are designed for systems up to 10,000 psi and are a perfect solution for instrumentation systems that require reliable shut-off at higher pressures. A great choice for OEM equipment including vertical separators, heater treaters and LACT units.
