Series 20 Model EL21

2-WAY NORMALLY OPEN

Hazardous Location — 2-Way Normally Open
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:

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 (EL21N7DCCP-N 24/DC) repair pack (2KEL21N-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.
