The CAT-3 DM1 Series E and CAT-4 DM2 Series E-pneumatic double valves are for exhausting downstream air to help meet the stop-time requirements in machine-guarding applications. The DM1 valves combine monitoring and airflow control functions into two identical valve elements for control category 3 applications. The DM2 valves integrate memory for control category 4 applications. The 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% of supply.
