Gestra Non-Return Valve: RK76 RK86 MB14
The GESTRA RK non-return valves must be installed between flanges. They are supplied with a spring and can be installed in any position. The RK 86 and RK 86A valves have a self-centring valve body with patented centring cams, which makes installation quicker, easier, and more cost-effective. These check valves are ideal for applications with liquids, gases, and vapours.
The GESTRA RK86 check valve backflow preventer is a robust and reliable solution for preventing backflow in pipework systems. It consists of a robust stainless steel, steel housing and a flap that opens when the medium flows in the direction of flow and closes automatically to block backflows. This backflow preventer is used in various industrial applications and is characterised by its high reliability and easy maintenance.
