HAZARDOUS LOCATION VALVES | Peter Paul Electronics Co., Inc.

PeterPaul explosion 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. Hazardous location 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.

*2-Way Normally Open Hazardous Location Valves* PeterPaul single orifice valves in which the orifice is closed in the energized position and no flow can exist between the inlet and outlet ports.
