Miniature Solenoid Valves provide compact 2-way on-off control for small fluid and gas handling systems where installation space is limited and fast automatic shutoff is required. This valve family includes plastic and stainless steel body options, while the operating design may be direct-acting or semi-direct acting, depending on the series and connection type.
Available sizes include 1/8 inch and 1/4 inch configurations, with female NPT and quick-connect connection styles depending on the series. As a result, these valves fit compact water, air, inert liquid, and compatible gas service where body and seal materials match the media.

Technical Specifications
Miniature Solenoid Valves are used where compact installation, low flow, and fast response matter more than larger-port capacity. However, exact values vary by series, body material, connection type, and coil selection, so buyers should confirm final selection against the applicable spec sheet.

Pressure, Temperature, and Media Fit
These valves are designed for compact flow control where small size and low-pressure operation matter. For example, the RSC threaded model uses a direct-acting design and can operate from 0 psi differential pressure. In contrast, the RSC push-in version uses a semi-direct acting design and requires a minimum of 3 psi for reliable operation. The stainless steel SS series also uses a direct-acting design and does not require a minimum pressure. However, small-orifice valves may not be suitable for gravity-fed applications. The RSSM Brass Series uses a direct-acting design that operates without minimum pressure requirements, making it suitable for compact fluid and pneumatic control systems with limited installation space.
Media compatibility varies by valve construction and seal material. For example, the RSC plastic series is designed for clean water and low-viscosity fluids, while the SS series handles inert liquids and gases, including water, air, weak acids, and diesel fuel, where materials are compatible. The RSSM Series supports water, air, light oil, and other inert media, making it well-suited for OEM automation equipment, pneumatic control assemblies, compact fluid control systems, dispensing equipment, and industrial utility applications. Always verify media compatibility, operating temperature, and material suitability before final valve selection.
Dimensions and Size Range
Dimensional fit can vary by series, connection style, and body construction, so buyers should review the applicable dimensional data before specifying for compact assemblies or tight equipment layouts. Specifically, RSC threaded models are available in 1/8 inch and 1/4 inch sizes, the RSC push-in model is available in 1/4 inch, the SS series is available in 1/4 inch female NPT, and the RSSM series is available in 1/8 inch and 1/4 inch sizes.
| Series | Body Material | Size Range | Notes |
|---|---|---|---|
| RSC Threaded | Polypropylene plastic | 1/8 inch to 1/4 inch | Direct-acting female NPT design |
| RSC Push-in | POM plastic | 1/4 inch | Semi-direct acting quick connect design |
| SS Series | Stainless Steel 316 | 1/4 inch | Direct-acting female NPT design |
| RSSM Series | Brass | 1/8 inch to 1/4 inch | Direct-acting female NPT design |

Series Options
RSC Plastic Series
The RSC Series covers compact plastic body valves used primarily for clean water and low-viscosity fluid service. The threaded model uses a direct-acting design with 0 psi minimum differential pressure, while the push-in model uses a semi-direct acting design and requires 3 psi minimum differential pressure. In addition, this series includes polypropylene and POM body constructions, EPDM sealing materials, and female NPT or quick-connect port options.
SS Stainless Steel Series
The SS Series is a compact stainless steel mini-solenoid valve for inert liquids and gases in 1/4 inch female NPT format. It uses a direct-acting plunger design, Stainless Steel 316 body construction, and a Viton seal. As a result, it suits compact installations where stainless construction and low-pressure operation are required.
RSSM Series
The RSSM Series supports water, air, light oil, and other compatible inert media across operating pressures up to 145 PSI and temperatures from 15°F to 250°F. Its direct-acting design allows reliable operation under low and zero differential pressure conditions, making it suitable for compact OEM, pneumatic, and industrial utility applications.

Technical Note
These valves are not intended for use in medical life support, combustion, aviation, aerospace, automotive, or similar applications. In addition, some miniature valves may be unsuitable for gravity-fed systems due to their small orifice size. Review final material and seal selection for media compatibility.
