Locking device DM 2®

ROSS CONTROLS® is proud to introduce its new line of DM 2® Series C Crossflow™ SERPAR® Double Valves with TOTAL Dynamic Monitoring & Memory for Category-3 & -4 Machine Guarding applications. ROSS’ new DM 2® Series C pneumatic safety valves meet all ANSI requirements for machine safety, including the Z244 lock-out, B11.19 machine guarding, and B155 packaging standards. The DM 2® Series C also meets stop-time requirements, and is Category-4, third party certified. Safety systems do not end at the wire! Memory, monitoring, and air-flow control functions are simply integrated into two identical valve elements. DM 2® Series C valves lock out due to asynchronous movement of valve elements during actuation or de-actuation, resulting in a residual outlet pressure of less than 1% of supply. Overt action is required for reset, and reset can only be accomplished by applying a remote air signal or by energizing the optional integrated electrical (solenoid) reset. The DM 2® Series C valves are base mounted, and available with BSPP or NPT pipe threads. Inlet and outlet ports on both sides of the bases provide for flexibility in piping. These new DM 2® Series C Valves are available in 4 sizes, providing a broad range of flow capabilities to meet your needs. Valves are designated by the nominal sizes 4, 8, 12, and 30 with outlet ports up to 2”. As a standard feature, the Status Indicator includes a pressure switch with both normally open and normally closed contacts to provide status feedback to the safety control system indicating whether the valve is in the lock-out or ready-to-run condition. Also, all models include a high flow, clog resistant silencer.
