Series 20 Model MLVH22 (FIXED POLARITY)
When the valve coil is energized, the plunger is drawn towards the sleeve end stop. The plunger is allowed to accelerate freely for a short distance before it makes contact with the shoulder of the sealing pin. Upon contact it imparts considerable force on the pin causing it to lift the seat. A return spring provides the return force, directly on the pin, to seal the orifice when the coil is enlarged with reverse polarity. The valve is for use on air and other non-corrosive gases, water and oil.
Neutral (−) a. Pulse Yellow lead to Positive (+) to latch b. Pulse Blue lead to Positive (+) to un-latch
Positive (+) a. Pulse Yellow lead to Neutral (−) to un-latch b. Pulse Blue lead to Neutral (−) to latch

* FKM seals not recommended for pressures of 500 psi and above.
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 example: valve (H22J7D3LM 12/DC) repair pack (KH22J3L DC)
