The MS valves by Festo have proven their worth at the maximum safety level with Performance Level "e". But not all machines and systems require these soft-start and exhaust valves in an emergency.
With immediate effect, the more attractively-priced safety valves MS6-SV
with Performance Level "c" are available with a higher venting capacity.
The core functionality of these safety valves MS6-SV-C
includes an electric on-off valve in combination with a soft-start valve. They are also suitable in limited construction space for a high pressurisation/exhaust flow rate on applications with medium safety requirements.
The safety valves MS6-SV-C and MS9-SV-C feature residual pressure-free venting and the freely adjustable pressure changeover point.
Due to their inherent soft-start function, unexpected movements by system components are avoided during start-up.
The safety valves fulfil SRP/CS Cat. 1, Performance Level "c" in accordance with DIN EN ISO 13849-1. MS6-SV-C and MS9-SV-C are also suitable for applications with low switching frequencies, such as venting after emergency-off pushbuttons, light curtains or door locks have been activated.
On the MS6-SV-C, the standard nominal flow rate (from 1 to 2) totals 5,700 l/min, and the venting capacity (from 2 to 3) totals 7,600 l/min. On the MS9-SV-C, the standard nominal flow rate (from 1 to 2) totals 16,500 l/min, and the venting capacity (from 2 to 3) totals 20,500 l/min.
