Series 50 ELW Model ELW53 - Exhaust to Atmosphere


3-Way Normally Closed Valve (Exhaust to Atmosphere)


A UL and CSA listed, low watt, miniature hazardous location valve with minimal space and energy requirements in volatile environments. Air and other fluids are compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.

  • Smallest hazardous location solenoid valve.
  • Best ambient and high temperature ratings on the market.
  • NEMA 4 rating is standard with encapsulated coil.
  • High quality engineering.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (ELW53JJ8DCCPL 120/60) repair pack (KELW53JJDL 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 (OELW53JJDDCCPL 120/60)

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.
