2-Way Normally Closed Valve
Super valves that have ratings that formerly required valves of much greater size. They have higher flow at low pressures and have quick media fill or dump for air, inert gases, and oil.
- Largest direct acting (non-piloted) valve we manufacture.
- Large orifice.
- High flow at low pressures.
- Gravity feed lubrication with quick media fill or dump.

Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (72B11DGM 120/60) repair pack (K72BD 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 (O72B11DGM 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.
