RSK

Our RSK check valve is our comprehensive answer to today’s demanding requirements. We have paid special attention to the robust design. The main difference compared to conventional check valves is that the valve disc and lever are not inside the body, but inside the cover, making it very user-friendly. Moreover, once the cover is removed, the valve body is fully exposed for any kind of inspection, even when it’s still installed in the system.
