Peter Paul Excellence
2-Way Normally Open Solenoid Valves

2-Way Normally Open

Peter Paul single orifice valves in which the orifice is open in the de-energized position and flow can exist between the inlet and outlet ports.

Peter Paul general purpose solenoid valves offer a wide range of control options over the flow of liquids and gases in applications from dispensing to instrumentation, commercial equipment, machinery, medical/dental equipment, control systems and off-highway equipment, to name just a few.

Peter Paul hazardous location valves are used where fire or explosion hazards exist due to the presence of flammable gases or vapors, flammable liquids, combustible dust, or easily ignitable fibers. Explosion Proof valves are recommended, or in some cases compulsory, where a high level of protection from explosion is required. For applications that require low power, a low watt version is also offered.
