Hi-Flo™ VP Valves (V Profile Valves)

Hi Flo Valve CPI Hi-Flo™ VP valves feature aerodynamic V-profiled rings that control and seal gas as it flows in and out of the compressor cylinder, providing increased efficiency and reliable operation in applications where temperatures and pressures are extreme.
The durable thermoplastic V-profile ring surface discourages the adherence of small particles of metal, sand or salt, providing improved performance over metal and non-profiled rings, which often become nicked, worn, cracked or warped. Each Hi-Flo™ VP valve is custom designed for its individual application to match specific compressor operating conditions.

Design Features

  •  Aerodynamic rings allow the free passage of foreign material and liquid slugs 
  • Springs are offered in chrome silicon and Hastelloy C materials
  • A balanced ported guard which allows an even flow around the circumference of the seat and provides an accurate location of spring pockets, essential for precise valve opening and closing. Seats and guards are offered in Ductile Iron and 4140 alloy steel for standard valves and in 17-4 stainless steel for corrosive applications
  • Internal center bolt features a simple, reliable design that is easy to assemble

Reliability Advantage

The Hi-Flo™ valves perform extremely well under the dirty gas and liquid slug conditions where flat ring valves typically fail. The aerodynamic angle of the Hi-Flo sealing element deflects any debris or liquid that may be present in the gas stream, virtually eliminating any build-up on the sealing surfaces.
