The model CV check valves have been developed for the requirements of the process industry. The wetted parts are suited specifically for applications with natural gas and aggressive fluids, but also for water and hydraulic oil.
The simple and robust design, with a safety factor of 4:1, enables model CV check valves a wide spectrum of use. The valve design and the high-quality sealing materials ensure high durability and tightness.
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. This principle of double sealing ensures reliable leak tightness.
