Founded in 1921, Ross Controls develops and produces high quality pneumatic valves & systems. It has over sixty years of experience designing & producing monitored redundant valves for safety applications. The DM2 is the latest control-reliable valve series for category 4 applications. The SV series has integrated double pole double throw switch to verify valve function for category 2 and 3 applications. For pneumatic energy isolation, the L-O-X® series provides a full line of manual lockout products. Ross safety-related products meet or exceed the global safety requirements for machine safeguarding and energy isolation and are supported by Ross' experienced global safety team. For robotic innovation, Ross developed one of the most advanced proportional pressure regulation units for faster, more precise robotic coating and dispensing applications, while reducing paint consumption, overspray and VOCs.

ROSS CONTROLS® Announces Updated Pneumatic Safety Certifications

POSTED 09/02/2009

ROSS CONTROLS® Announces Updated Pneumatic Safety Certifications(TROY, MI) – ROSS CONTROLS is pleased to announce that its DM2® Series C safety valves have received third-party certification from the BG (Berufsgenossenschaften- German Institute for Occupational Safety and Health). On July 8, 2009, the BG deemed the DM2® Series C products suitable for ISO 13849-1:2006 Category 4 PL e applications. The ISO 13849-1:2006 standard (Safety of Machinery, Safety-related Parts of Control Systems) will replace the EN 954-1 standard as of November 30, 2009. This certificate is available on the ROSS Web site at or upon request from ROSS Customer Services.

All valves in the ROSS DM2® product line 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 DM2® pneumatic double valve family to address this issue knowing that effective safety systems do not end at the electrical wire.

For enhanced performance and value, memory, monitoring, and airflow control functions are simply integrated into two identical valve elements. DM2® pneumatic safety valves lock out due to asynchronous movement of valve elements during actuation or de-actuation, resulting in a residual outlet pressure of less than one percent of supply. Overt action is 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 base-mounted and are available in 1/2” to 1-1/2” ports sizes with NPT or BSPP threads.

Additionally, all DM2® valves will be labeled with the CE (Conformite Europeenne) mark to comply with the New Machinery Directive (2006/42/EC) that takes effect in the European Union as of December 29, 2009. This directive defines the requirements for the CE marking of products, requires the CE mark on safety components, and specifically includes “…valves with additional means for failure detection intended for the control of dangerous movements on machinery.” The “Declaration of Conformity” document is available on the ROSS Web site at or upon request from ROSS Customer Services.

CE marking is not required for standard pneumatic devices and, as such, ROSS does not specifically mark all products. However, declarations of conformity to the applicable standards are available upon request for ROSS’ other product lines.
