2-WAY NORMALLY OPEN 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 400 psi — 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 400 psi.
- Quality design and construction.

Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (151J2XGM 120/60) repair pack (K151JX 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 (O151JDXGM 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 15 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.
