Series MLV20 Model 22 3-Wire

2-WAY NORMALLY CLOSED

2-Way Normally Closed 3-Wire 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 (-)
1. Pulse Yellow lead to Positive (+) to latch
2. Pulse Blue lead to Positive (+) to un-latch
Common Black wire set to Positive (+)
1. Pulse Yellow lead to Neutral (-) to un-latch
2. 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. for 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)
