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

Ross Controls

(TROY, MI) – ROSS CONTROLS is pleased to announce that its CAT-3 DM1 Series E and CAT-4 DM2® 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 DM2® 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 or upon request from ROSS Customer Services.

All valves in the ROSS DM1 and DM2® 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 DM2® 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 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 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 inline mounted 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. For more information or for a free brochure about the DM1 or DM2® Series E double valves, contact your local ROSS distributor, ROSS Customer Service or visit ROSS' web site.
