RK Disco check Valves

The spring-assisted DISCO® non-return valve opens when the opening force exceeds the closing force.
The opening force depends on the pressure or the volume flow, and the closing force on the tension of the closing spring,
on the closing weight, on the installation position and the size of the non-return valve.

BB Dual-Plate Check Valves

Our dual-plate check valves BB 3 are developed to ensure the best possible system safety by preventing return flows.
Partial opening of the plates remains stable even with a low flowrate. Consequently, the BB 3 can be used without problem even in
conditions of fluctuating loads. Thanks to its low weight, the dual-plate check valve is quick and easy to install.
