2-WAY NORMALLY CLOSED Valve
Our original mini — engineered for space economy without sacrificing performance. Typical applications include medical, analytical instrumentation. Air, water, and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, and many oils require special seal materials.
- Tough with options to use in hazardous location environments or low watt applications.
- High quality engineering.

Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (52J8DGM 120/60) repair pack (K52JDD 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 (O52JDDGM 120/60)
Operating Conditions

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.
