2-Way Normally Closed 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 de-energized. The valve must be mounted 30 degrees of vertical and 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.

Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (H22J7DGMG 120/60) repair pack (KH22JD AC)
When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (OH22JDDGMG 120/60)

Cv Flow Formulae
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.
