3-WAY DIRECTIONAL CONTROL Valve
3-Way Directional Control Reverse Polarity Valve - This type of valve is often used in remote areas where continuous power may not be available or with battery-powered portable equipment where power capacity is limited, as it only uses power during latching and un-latching. It is also valuable in equipment where coil heating, due to continuous application of power, is undesirable. Air and other fluids are compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.
- Pulse Yellow lead to Positive (+) to latch
- Pulse Blue lead to Positive (+) to un-latch
- Pulse Yellow lead to Neutral (−) to un-latch
- Pulse Blue lead to Neutral (−) to latch

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.
