Dwyer Series P4 PPS Piston Flow Switch

Dwyer Series P4 Flow Switch features a molded plastic construction for enhanced performance. Monitor liquids with fixed set points from 0.1 to 1.5 GPM. Choose normally open or normally closed SPST or SPDT hermetically sealed reed switch technology.

Dwyer Series P4 PPS Piston Flow Switch

The industrial switch features PPS (polyphenylene sulfide) R4 housing and piston, 316SS spring, fluoroelastomer O-ring, and Epoxy. The inlet and outlet ports are 9/16"-18 UNF- 2B thread with optional 1/8" and 1/4" NPT or 1/2" barbed adapters.

Shuttle or piston flow switches are sensors with an electrical contact output at a specific flow rate. Models are used with oil, air, water, and gases. Applications include oil flow control, low flow detection in cooling lines, and high-pressure lubrication systems. Rugged construction and excellent chemical compatibility simplify flow/no flow detection.
