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 (N72R9DCP 120/60) repair pack (KN72RDD 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 (ON72RDDCP 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.)*
Valve Temperature Range
Standard Valves – 0°F (-18°C) to 104°F (40°C) ambient; 0°F (-18°C) to 150°F (65°C) media. Optional Valves – can tolerate much higher or much lower ambient and media temperatures.*

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.
