ROSS DM2® Control Reliable Double Valves

The ROSS Controls DM2® Control Reliable Double Valves act as a pneumatic safety relay and are 3rd party certified to Category 4 performance level E.  They meet SRP/CS (Safety Related Parts of the Control System requirements) for relevant ISO, ANSI, and CSA safety standards.
The DM2® valves feature a 3/2 Normally Closed safety pneumatic exhaust function, dual channel, and are internally self-monitored.  They include a status indicator to monitor its readiness status and requires a dedicated reset in the event that a fault occurs to unlock the valve  and return it to its normal ready-to-run status.
These valves feature excellent response time and flow rates, are available in port sizes ¼” – 1 ½” with NPT or BSP threads, and are available with explosion proof coils and status indicators for industries and environments where electrical ignition safety is a concern.
