Slow-Start Air-Exhaust Valves for Wilkerson Modular Compressed Air Filter/Regulator/Lubricators (FRLs)
 |
Also known as Monday-morning valves, these valves slowly introduce pressure to reduce surge damage during start-up. When the solenoid is shut off, the valve cuts air to your equipment by exhausting downstream pressure. To ensure compatibility, the valve series number should match the series number on your Wilkerson components.
