The model HPCV high-pressure check valves have been developed for high-pressure applications of 15,000 to 60,000 psi [1,034 to 4,136 bar].
The wetted parts are suited specifically for applications with natural gas and aggressive media, but also for water and hydraulic oil. The simple and robust design enables model HPCV check valves a wide spectrum of use. The valve design and the high-quality sealing materials ensure high durability and leak tightness.
Redundant sealing
The sealing element (piston) has a double sealing system from an elastic O-ring and a metal cone.
With any back pressure, the soft O-ring and then the sealing face of the metal cone prevent the reverse flow of the medium. The sealing concept is designed for demanding applications in the chemical, petrochemical and the oil and gas industries where high performance and reliable leak tightness is required.
Metal seat
This design is preferably used with corrosive or abrasive media like water and oil in very high temperature applications. The absence of soft sealing material is key for the long endurance of the metal seat.
