3-Way Normally Open

3-WAY NORMALLY OPEN VALVE

PeterPaul dual orifice valves in which the body orifice is closed and sleeve orifice open in the de-energized position. No flow can exist between exhaust and cylinder ports but flow does exist between inlet and cylinder ports.

Hazardous Location 3-Way Normally Open Valves

PeterPaul 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.

Series/Model Std. Port Size Pressure (PSI) Flow (CV) Size (h x w)" Watts
20/E24 1/8" or 1/4" NPT 0 - 400 .024 - .227 4.0 x 2.63
20/EL24 1/8" or 1/4" NPT 0 - 400 .024 - .156 3.98 x 2.59 1.8
E50/E54 1/8" NPT 0 - 150 .022 - .156 3.27 x 2.25
70/N74 1/4" NPT 0 – 350 .09 - .78 3.42 x 2.69

Low Watt 3-Way Normally Open Valves

PeterPaul low watt valves are general purpose or safety valves for pneumatic and hydraulic applications. The versatility of these valves is increased to include the handling of hot air, hot water, refrigerants and many other media, by the use of different seals.

Series/Model Std. Port Size Pressure (PSI) Flow (CV) Size (h x w)" Watts
20/EL24 1/8" or 1/4" NPT 0 - 400 .024 - .156 3.98 x 2.59 1.8
58/584 Manifold Mt. or 10-32 0 - 300 .010 - .034 2.26 x 1.06 3.5

High Pressure 3-Way Normally Open Valves

PeterPaul high pressure valves operate with a pressure between 1000 and 3000 PSI. Medical, Laboratory, Instrumentation and Industrial companies, etc. that require high pressure bottled gas with media such as 02, C02 and compressed Nitrogen use our valve in various applications.

Series/Model Std. Port Size Pressure (PSI) Flow (CV) Size (h x w)"
20/H24 1/8" or 1/4" NPT 0 - 1000 0.024 3.48 x 1.69
