Series 20 Model MLVH22 (3-wire)

2-WAY NORMALLY CLOSED

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.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (H22J7DELM 24/DC) repair pack (KH223D LM)

When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (OH22JDDELM 24/DC)
