Festo introduced the MS6-SV and MS9-SV safety valves. These safety valves offer many features, including compact size, soft start functionality, and advantageous price versus performance ratio. The MS6-SV is available in Performance Level c and e units; the MS9-SV is available in a Performance Level c unit.
Both the MS6-SV and MS9-SV have integrated soft start and exhaust functions in a compact unified body. OEMs and end users have the flexibility of mounting these safety valves as stand-alone units or as a component of the modular Festo MS air preparation system.
The MS6-SV-E series is certified to the DIN ISO 13849-1 safety standard – category 4, performance level e. This valve has an extremely high exhaust rate for its size – 9,000 l/min from P2 to P3. The valve delivers continuous testing and sensing of the safety function.
The MS6-SV-E-ASIS valve option has an integrated network connection to AS-Interface Safety at Work, which eliminates the need for an additional safety relay. The ASIS valve option includes switching status sensing and diagnostic functions. The input and output pressures P1 and P2 are internally monitored and can be read via the AS-Interface bus.
C-level safety valves
The MS6-SV-C and MS9-SV-C are ideal for applications with performance level c safety requirements. The c series valves are reliable, cost-effective, single channel safety units designed to enable fast safety exhaust.
Flow rates for the MS6-SV-C used for station level safety:
- P1 > P2 5,700 l/min
- P2 > P3 7,600 l/min
Flow rate for the MS9-SV-C applied at the machine level:
- P1 > P2 15,500 l/min
- P2 > P3 20,500 l/min
Both have adjustable pressure ramp-up rate and switching point.
Mount with the Festo MS series air preparation units
The Festo MS air preparation series combines all of the standard functions of air preparation with additional options for pressure regulators, filters, dryers, sensors, lubricators, and safety with the MS6 and MS9 safety valves. The MS air preparation series includes function modules with integrated sensors, remote adjustability, and remote-controlled pressure monitoring for maximum process security.
