2-WAY NORMALLY CLOSED Valve
2-Way Fixed Polarity Magnet Latching Valve - 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, water and other fluids are compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require other seal materials.
There are two ways to latch and un-latch the valve.
- Common Black wire set to Neutral (-)
- Pulse Yellow lead to Positive (+) to latch
- Pulse Blue lead to Positive (+) to un-latch
- Common Black wire set to Positive (+)
- Pulse Yellow lead to Neutral (-) to un-latch
- Pulse Blue lead to Neutral (-) to latch

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. Examples: valve (151J2XGM 120/60), repair pack (K1513X 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 (O151JDXGM 120/60)

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.
