Series 20 Model E23

Hazardous Location
3-Way Normally Closed Valve (exhaust to atmosphere)

Peter Paul explosion proof 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.

• Explosion Proof
• The flagship valve initially created for fluid power industry.
• Heavy duty and made of stainless steel.
• A real workhorse with proven performance.
• It has the greatest amount of options available of all the valves.
• Wide range of orifice sizes from 1/32" to 1/4".
