ROSS – SV27 Series Directional Control Valve

Air/Dump Release Safety Function

The SV27 Series Directional Control Valve Sensing Valve uses a safety-rated DPST (Double-Pole Single-Throw) switch to monitor the valve’s operating position.

The SV27 valve can be used for safe shut-off and exhaust functions for Category 2 applications with proper integration and monitoring. The feedback switch informs the controls that the valve internals have shifted properly.
