Series MLV20 Model 25 3-Wire

3-WAY DIRECTIONAL CONTROL

3-Way Directional Control 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.

Common Black wire set to Neutral (-)
1. Pulse Yellow lead to Positive (+) to latch
2. Pulse Blue lead to Positive (+) to un-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 (25JJ7XELM 12/DC) repair pack (K25JJ3L DC)
