General Service Solenoid Valves provide 2-way on-off control for inert liquids and gases in low-pressure and general industrial fluid handling systems. This valve family is available in brass and stainless steel body constructions, with normally closed and normally open options, female NPT connections, and multiple AC and DC coil voltages.
Available sizes range from 3/8 inch to 2 inch in brass and 1/2 inch to 2-1/2 inch in stainless steel, depending on series and configuration.

Pressure, Temperature, and Media Fit
These valves are designed for inert liquids and gases, including water and air, when the body and seal materials match the media. For water service, the valve can operate from 0 psi differential pressure. For air service, the valve requires a 7 psi minimum differential pressure for reliable operation.
Operating temperature ranges from 15 to 250°F, and maximum pressure depends on valve size, current type, and whether the valve is normally closed or normally open. Review chemical compatibility before making the final selection.
Dimensions and Size Range
Dimensional fit can vary by series, valve action, and pipe size, so buyers should review the applicable dimensional data before specifying for equipment clearances or tight piping layouts. Brass body BZW configurations cover 3/8 inch to 2 inch, while stainless steel SZW configurations cover 1/2 inch to 2-1/2 inch, with dimensional data provided by size for both normally closed and normally open versions.
| Series | Body Material | Size Range | Notes |
|---|---|---|---|
| BZW | Brass | 3/8 inch to 2 inch | 3/8 inch is normally closed only |
| SZW | Stainless steel | 1/2 inch to 2-1/2 inch | 2-1/2 inch normally open is special order |

Series Options
Brass Body, BZW Series
The BZW Series is the brass body option in this valve family. It is a 2-way semi-direct acting valve with female NPT connections, Viton diaphragm seal, and available normally closed and normally open configurations. Brass body sizes range from 3/8 inch to 2 inch, with the 3/8 inch size available in normally closed only.
Stainless Steel Body, SZW Series
The SZW Series is the stainless steel body option in this valve family. It is also a 2-way semi-direct acting valve with female NPT connections, Viton diaphragm seal, and available normally closed and normally open configurations. Stainless steel sizes range from 1/2 inch to 2 inch in standard coverage, with a 2-1/2 inch normally open special-order variant shown in the sheet.
