Wall or Panel Mounted Pneumatic, four-port, snap acting relay, SPDT
Overview
The four port, snap acting relay, converts a proportional air pressure change, from a controller to a positive (two-position) pressure change. It can also divert a supply line to one of two branches.
Features
- Manually adjustable switching pressure.
- Sharp barb connections for 5/32 inch (4 mm) O.D. plastic tubing.
- Molded plastic construction with neoprene diaphragms and stainless steel lever.
- Mounts in any position with mounting clip.
