ROSS CONTROLS® Announces Updated Pneumatic Safety Certifications
Ross Controls Posted 09/02/2009
(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 www.rosscontrols.com 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 www.rosscontrols.com 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.
