3-Way Directional Control Valve
The little black box — magnetic components encased in epoxy for durability and reliability. Interior parts are stainless steel and anodized aluminum. The valves may be used with air, inert gas and liquid media at pressures from vacuum to 300 psi AC, 200 psi DC — depending upon orifice size and configuration. For those who require extra heat resistance and media compatibility, FKM and other elastomers are available.
- Small, lightweight and economical.
- Operating pressures from vacuum to 300 psi AC, 200 psi DC.
- Quality design and construction.

Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (155HH2XGM 120/60) repair pack (K155HX 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 (O155HH2DGM 120/60)
Operating Conditions

Cv Flow Formulae
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.
