GESTRA applies a so-called lapping technique where the sealing surface of each closing disc is finished separately by grinding that makes the valve so tight that it can also be used as a vacuum relief valve in the piping. The non-return valves of the Disco model suit in the best way for small pipes, because their flow resistance in relation to other flanged non-return valves will rise as the pipe size increases. In addition to the lapping of the seal surface, the material selection is also wide. There are different materials for the body, the flap and the spring. Therefore, it is possible to design tailored solutions, for example, so that the spring of the non-return valve is made of Hastelloy, and the other parts are made of acid-proof steel.

Gestra RK86 DN40 C.Steel Wafer Check Valve

They ensure optimum, uniform pressure at the flange sealing surfaces at both inlet and outlet , so that you can rely on trouble-free plant operation. Antistatic connections are demanded, especially in the chemical industry, for certain parts of the plant to prevent any accumulation of static charge. Our experience gives you the quality, our visions give you the innovative energy. On this foundation, GESTRA has developed a non-return valve for industrial applications that combines many requirements in a single valve — and therefore not only fulfils but also far surpasses your wishes and expectations.
