The Series P4 PPS Piston Flow Switch is designed for detecting fluid flows at fixed set-points. It uses a piston actuator, sealed reed switches (SPST or SPDT), and rugged materials including PPS housing, 316 stainless steel springs, and fluoroelastomer O-rings. Ports are threaded, with optional adapters, making it versatile for many piping setups.

Fixed set-point switching from ~0.1 to 1.5 GPM

Choice of switch types: SPST or SPDT

Durable materials: PPS housing, stainless steel, fluoroelastomer seals

Optional adapters for different thread types or hose barb connection

Hermetically sealed reed switch protects internal contacts

Applications:

Pump protection (detecting when flow drops below threshold)

Cooling systems, lubrication circuits, or fluid process lines

Situations where flow needs to trigger alerts or controls

OEM or retrofit applications where fixed flow detection is required
