Series 20 Model MLVH22 (REVERSE POLARITY)


2-Way Reverse Polarity Magnetic Latching Valve - 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 energized with reverse polarity. The valve is for use on air and 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 coil 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)

PeterPaul has created this page for you so you can calculate the flow or Cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points of a liquid/gas carrying network) and the flow rate.

The use of this flow coefficient (Cv) calculator offers a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have a large impact on the performance of the assembly for transferring gas or liquids in the system.

Our sales department is ready to answer questions and to solve your valve needs. Please feel free to call, chat or email us.
