The CV non-return valve for pressure gauges was designed to meet the needs of the process industry. The wetted parts are particularly suitable for use with natural gas and aggressive liquids, as well as water and hydraulic oil.

The simple and robust design with a safety factor of 4:1 allows a wide range of applications. The valve design and high-quality sealing materials ensure high durability and tightness. The sealing element has a double sealing system consisting of an elastic ring and a metal cone. In the event of back pressure, an elastic ring and metal cone prevent the media from flowing back. This type of double-sealing system ensures a reliable seal.
