Peter Paul Magnetic Latching Valve Model MLVH22

Peter Paul Magnetic Latching Valve Model MLVH22

PeterPaul single orifice valves feature an orifice that is closed in the de-energized position, preventing any flow between the inlet and outlet ports. When the valve coil is energized, the plunger is drawn towards the sleeve end stop. It accelerates freely for a short distance before contacting the shoulder of the sealing pin, imparting considerable force on the pin and causing it to lift the seat. A return spring directly acts on the pin to seal the orifice when the coil is de-energized. These valves are suitable for use with air, other non-corrosive gases, water, and oil.

Kel-F pin sealing element.
Orifice guides the sealing pin for perfect alignment.
Simple construction…only two moving parts.
Through the use of a permanent magnet, the latching valves are bi-stable in either shifted state. This allows the valve to stay in either state indefinitely without drawing power. To shift the valve from one state to another, a short 50 millisecond DC voltage is applied to the coil. To shift the valve back, a reverse polarity pulse is applied to the coil. This feature makes this valve suitable for use in remote areas where continuous power may be limited. It is also valuable in equipment where coll heating. due to a continuous application of power, is undesirable such as in medical and chemical analyzers.

Ordering Information:

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (H22J7DELM 24/DC) repair pack (KH22JD 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)
