3-WAY NORMALLY CLOSED (e to a) Valve
PeterPaul’s model H23 has a dual operator valve that allows the same media control as a three-way normally closed valve but at much higher pressure ratings than previously available. To function as a 3-way normally closed valve, operators must be alternately energized and de-energized. Pressure applied to the “IN” port must always be equal to or greater than the pressure in the “CYL” port. Air and other non-corrosive gases, water, and oil.
- Made for higher pressure ratings.
- Precision stainless steel, free-floating plunger.
- Kel-F pin sealing element.
- Orifice guides the sealing pin for near-perfect alignment.

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.
