BG Certifies ROSS' DM1 and DM2® Series E Size 2 Double Valves

Press release date: February 26, 2013

TROY, MI -  ROSS CONTROLS is pleased to announce that its CAT-3 DM1 Series E and CAT-4 DM Series E size two double valves have received third-party certification from the BG (Berufsgenossenschaften– German Institute for Occupational Safety and Health). On September 14, 2012, the BG deemed the DM1 Series E and DM Series E size two products suitable for DIN ES ISO 138491 PL d and DIN ES ISO 138491 PL e (respectively) applications. These certificates are available on the ROSS web site at www.rosscontrols.comor upon request from ROSS Customer Services.

All valves in the ROSS DM1 and DM product lines meet global requirements for machine safety and are commonly used for exhausting the downstream air to help meet stop-time requirements in machine guarding applications. Because many safety systems incorrectly focus solely on the electrical design and overlook mechanical elements, ROSS created the DM1 and DM pneumatic double valve families to address this issue knowing that effective safety systems do not end at the wire.

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% of supply.

For enhanced performance and value, the DM Series E products integrate memory into this combination for control category 4 applications. DM 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 one percent of supply. Deliberate action is then required for reset, and reset can only be accomplished by applying a remote air signal or by energizing the integrated electrical (solenoid) reset.
These ROSS safety valves are inlinemounted and are available in 1/4” to 3/8” ports sizes with NPT or BSPP threads. Silencers are included (attached to the valve’s 1/2 exhaust port) and optional status indicators are also available.
