3-Way Normally Closed Valve (Exhaust to Atmosphere)
PeterPaul explosion-proof solenoid valves are used where fire or explosion hazards exist due to the presence of flammable gas or vapors, flammable liquids, combustible dust, or easily ignitable fibers. The low-watt feature assures low power consumption, reducing drain on electrical systems. This is a benefit for renewable energy applications and where the solenoid valve must be on continuously.
- Heavy-duty and made of stainless steel.
- A real workhorse with proven performance.
- Low power consumption — best for renewable energy and limited-resource applications.
- Wide range of orifice sizes, from 1/32″ to 1/8″.

Ordering Information:
* Rating may vary based on an elastomer choice.
Seal Material: Replace ∆ with desired code - Blank = Nitrile (Buna) S = Low Temp Buna. N = FKM* E = Neoprene A = EPDM
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (EL23NN9DCCP-N 24/DC) repair pack (2KEL23KKD-N DC)
When ordering operators add the letter “O” to the front of the valve number, and the body code will change. Contact the factory for the complete part number.

Cv Flow Formulae
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.
