Series 20 Model MLV23 (REVERSE POLARITY) - Exhaust to Atmosphere


3-WAY NORMALLY CLOSED (e to a) Valve


3-Way Normally Closed Magnet Latching Valve — Exhaust to Atmosphere This type of valve is often used in remote areas where continuous power may not be available or with battery-powered portable equipment where power capacity is limited. It is also valuable in equipment where coil heating, due to continuous application of power, is undesirable. Air and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.

  • Valve is magnetic latching.
  • Meets today's demand for economy of space.
  • Uses power only during latching and un-latching.
  • Great for medical and chemical analyzers.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (23JJ7DELM 12/DC) repair pack (K23JJDL DC)

When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (O23JJDDELM 12/DC)

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.
