The DM1 Series E and DM2 are suitable for DIN ES ISO 138491 PL d and DIN ES ISO 138491 PL e applications, respectively. All DM1 and DM2 valves aid stop-time requirements in machine guarding applications. The DM1 Series E valves combine monitoring and airflow control functions into two identical valve elements for control category 3 applications. If asynchronous movement of valve elements occurs during actuation or deactuation, the valve exhausts downstream air, which results in a residual outlet pressure of less than 1 percent of supply. DM2 Series E products integrate memory into this combination for control category 4 applications. DM2 pneumatic safety valves lock out due to asynchronous movement of valve elements during actuation or deactuation, also resulting in a residual outlet pressure of less than 1 percent of supply. Deliberate action is required for reset, which can only be accomplished by applying a remote air signal or by energizing the integrated electrical (solenoid) reset. The valves are inline mounted and are available in ¼-in. to 3/8-in. ports sizes with NPT or BSPP threads.
