Soft-start/quick exhaust safety valve from Festo

The MS6-SV-C offers high flow rates in a compact size. As a result, Festo says it can vent air in a system quickly and reliably, offering machine builders enhanced safety. Designed for applications with low switching frequencies, the safety valve is suitable for medium to low risk systems and has certification up to performance level C in accordance with DIN EN ISO 13849-1. Thanks to its soft-start function, unregulated movements by system components are avoided during start-up and the system contains no residual pressure once vented. There are two valves in the range, the MS6-SV-C and MS9-SV-C, which are compatible with either 60 or 90mm grid size MS series air preparation ranges. The MS6-SV-C has a standard nominal flow rate of up to 5,700 l/min and a venting capacity of up to 7,600l/min. The MS9-SV-C delivers a higher standard nominal flow rate of up to 16,500l/min, and venting capacity up to 20,500l/min.
