pilot3/2-wayspring-return

Medium Filtered, oil-free and dried compressed air according to ISO 8573-1:2010, Class 7:2:4, instrument air, free of aggressive additives. Alternatively the pressure dew point must be at least 10°C below lowest occurring ambient temperature. Materials Body: Al (anodized), seals: NBR and POM, inner parts: Al, stainless steel and brass This valve may be used either normally open or normally closed. Normally closed: pressure inlet port 1 (P). Normally open: pressure inlet port 3 (R). A signal arriving at 12 (Z) switches the flow of the valve from 1 (P) to 2 (A) and closes port 3 (R) after the set time has expired. Instead of supplying main pressure to either port 1 or 3, the branched signal line can be connected to 1 or 3. The signal line to port 1 or 3 must not be longer than the signal line to port 12.
