2-Way Normally Open Valve
This valve uses a pin style seal. The pin is guided into the orifice. 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 three moving parts.

Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (H21M7XGV 120/60) repair pack (KH21MX 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 (OH21MDDGV 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.
