ROSS announces their 21 & 27 Series in-line valves are now Safety Integrity Level (SIL) Certified per the requirements of the IEC 61508 2010 standard. These valves are suitable for use in safety instrumented systems up to SIL 2 and may be used in a redundant structure up to SIL 3.
The third party assessment and certification by TÜV Rheinland Industrie Service GmbH ensures that the valves and safety manual comply with the IEC 61508 standard. This standard provides safety equipment suppliers and users a common framework to design products and systems for safety-related applications.
The ROSS 27 Series in-line valves have a robust poppet design for near zero leakage & high dirt tolerance. This construction promotes self-cleaning and is wear compensating enabling a high level of repeatability throughout the life of the valve. These valves are available in port sizes ranging from ¼” to 2 ½”, with either solenoid or pressure control, and are available in either a 2/2, 3/2, or 4/2 function.
The ROSS 21 Series valves are configured like the 27 Series for use in applications that require either a high or low temperature rating. This added feature is accomplished with metal internals and special seals that are appropriate for use in more extreme temperatures.
