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.

Non-Return Check Valve From Gestra

Gestra check valves, specifically models RK86, RK86A, MB14 and RK76, are highly regarded for their robust performance in preventing backflow in various industrial applications. These valves are often used in steam, water and gas systems where maintaining unidirectional flow is critical. The RK86 and RK86A models are praised for their compact design and reliable operation in high-pressure environments. The MB14 model, known for its versatility, is often used in both liquid and gas systems, ensuring operational efficiency and safety. The RK76 model, designed for heavy-duty applications, offers excellent wear resistance, making it ideal for continuous operation in demanding conditions. The main advantage of Gestra check valves is their durability, ease of maintenance and their ability to increase system reliability by preventing backflow, protecting critical equipment and minimising downtime.
