2-WAY NORMALLY CLOSED Valve
PeterPaul 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".

Seal Material: Replace ∆ with desired code - Blank = Nitrile (Buna) S = Low Temp Buna. N = FKM* E = Neoprene A = EPDM
+ Ratings in brackets are optional extended ratings; consult factory.
Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (E22N9DCCM 120/60) repair pack (2KE22K AC)
When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (OE22NDDCCM 120/60)
Operating Conditions
- Media
- Air, water, and other fluids compatible with standard Buna seals. Hot water, steam gasoline, and many oils require special seal materials. (Series 20 pressure ratings may change due to the viscosity of the liquid.)*
- Valve Temperature Range
- Standard Valves – 0°F (-18°C) to 104°F (40°C) ambient; 0°F (-18°C) to 150°F (65°C) media. Optional Valves – can tolerate much higher or much lower ambient and media temperatures.*

PeterPaul has created this page for you so you can calculate the flow or Cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points of a liquid/gas carrying network) and the flow rate.
The use of this flow coefficient (Cv) calculator offers a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have a large impact on the performance of the assembly for transferring gas or liquids in the system.
Our sales department is ready to answer questions and to solve your valve needs. Please feel free to call, chat or email us.
