3-Way Normally Closed Valve (Piped Exhaust)
Super valves that have ratings that formerly required valves of much greater size. Air, water, and other fluids are compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials.
- Largest direct acting non-piloted valve we manufacture.
- Large orifice.
- High flow.
- Will operate effectively at very low pressures or vacuum.

Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (73OO9ZGM 120/60) repair pack (K73OOX 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 (O73OODDGM 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.
