2-Way Normally Closed Valve
2-Way Large Orifice, Internally Piloted, Reverse Polarity Magnet Latching Valve - PeterPaul offers a line of large orifice solenoid valves to address process industry requirements for high flow rate or quick dump and fill capacity. These DC powered valves are also suited for gas and liquid applications. Port sizes for pilot lift, two-way normally closed versions range from 1/2” to 3” NPT, with pressure ratings from 3 to 200 PSI.
- Large orifice sizes for high flow applications.
- Body is made of brass forgings or 316 stainless steel.
- Operates on differential pressure — internal pilot.
- NPT threaded connections.
- Same coils and housings as our popular 20 Series.

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.
