The FESTO MS series features manually operated on-off valves for pneumatic installations, allowing pressure to gradually build up when turned on and then rapidly venting air when turned off. The rotary knob can be fitted with a padlock when switched off to prevent tampering, and at connection port three a silencer can be fitted. A pressure gauge or sensor can be installed for optional system monitoring and a module connector for connection to MS4 or MS6 combination air preparation units is available.
