1/4 in Stainless Steel Solenoid Valve Body

This 1/4 inch stainless steel solenoid valve body is designed for fluid control in plumbing and industrial systems. It operates as a two-way, two-position valve with a normally closed configuration. The body material resists corrosive environments and suits indoor or outdoor installation. It handles air, inert gas, and water up to a maximum pressure differential of 500 psi.

Simple thread-in installation

The valve body connects via standard 1/4 inch nominal pipe threads for straightforward integration. A separate coil must be sourced and matched to the required voltage and actuation type. The 1/16 inch orifice and 0.12 Cv rating limit flow capacity, so verify system demand before fitting. Ensure the fluid temperature does not exceed 180 degrees Fahrenheit to avoid seal damage.

Suits low-flow corrosive fluid control up to 500 psi

This valve suits engineers and maintenance teams managing low-flow air, inert gas, or water lines in corrosive settings. It is not intended for high-volume flow applications or media exceeding the stated temperature and pressure limits. Buyers needing larger orifice sizes, higher Cv values, or integrated coil assemblies should consider alternative valve bodies.

Questions about this item

How can I verify the valve is operating correctly after installation?

Apply air or inert gas up to 500 psi differential and confirm the valve opens when energised and closes when de-energised; water service up to 500 psi differential should show the same response.

What components are included and what must be purchased separately?

The package contains the stainless steel valve body only; a compatible solenoid coil must be bought separately to complete the assembly.

Which orifice size and Cv rating should I select for my flow requirements?

This model provides a 1/16 in orifice with a Cv of .12, suitable for low-flow air, inert gas or water applications up to 180 °F.
