2-Way Normally Closed Valve
PeterPaul offers large orifice solenoid valves to address process industry requirements for high flow rate or quick dump and fill capacity. These AC or DC powered valves are suited for gas and liquid applications. Port sizes for pilot lift, two way normally closed 1/2” to 1” NPT, with pressure differentials from 3 to 200 PSI.
- Large orifice sizes for high flow applications.
- Body materials as listed.
- Pilot operated.
- NPT threaded connections.
- Same coils and housings as our popular 20 Series.

Ordering Information:
Seal Material: Replace ∆ with desired code - L = Nitrile (Buna) S = Low Temp Buna. N = FKM* E = Neoprene A = EPDM
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (828B12DGM 120/60) repair pack (K828B12DD AC)
No operator available

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.
