Ordering Information:
Seal Material: Replace ∆ with desired code - Blank = 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 (N71P9ZCP 120/60) repair pack (KN71PDX 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 (ON71PDDCP 120/60)
Operating Conditions
- Media
- Air, water, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials. (Series 70 pressure ratings may change due to the viscosity of the liquid.)*

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.
