2-WAY NORMALLY CLOSED Valve
General purpose or safety valves for pneumatic applications. The versatility of these valves is increased to include the handling of hot air, refrigerants, and many other media by the use of different seals. Air and other gases are compatible with standard Buna seals.
- General purpose valve with reduced power consumption.
- Increased versatility.
- For pneumatic applications.
- Increased capability to handle hot air and other gases.
- High quality engineering.

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.
