CPV O-Seal Valves

CPV O-SEAL  System 6000 psi Valves

What separates these flat-faced, soft seated valves from others is their reputation for leakproof reliability and long service life.  They also provide low torque and a hand tighten positive bubble tight seal.  The entire O-SEAL line of shut off, needle, check and relief valves are rated for vacuum to 6000 psi (413 BAR) in liquid or gas service.  Depending on the seal material selected, these valves will function from -65°F (-54°C) to 400°F (204°C). They also handle the most elusive gases such as helium and hydrogen.  O-SEAL valves can accommodate pipe and tube sizes from 1/8” to 2”.

The unique CPV O-SEAL System design employs a flexible O-ring that is recessed into a close tolerance groove on each of the flat-faced union ends for slip in, slip out convenience. This creates a bubble tight seal that can withstand heavy vibration or pressure surges far better than gasket or metal-to-metal type seals. O-SEAL System Valves also provide users a cost-of-maintenance advantage by having a completely interchangeable valve cartridge.

The soft goods in the cartridge is removable and can be specified in different materials for special applications.  The software group is determined by compatability with the liquid or gas and the temperature range of the application. Because the cartridge is easily removed from the valve for maintenance or replacement, the cost of purchasing a new valve can be avoided.  In most cases, the old cartridge can be serviced off-line with a new soft goods kit for re-use another time.
