Steam Solenoid Valves provide 2-way on-off control for steam, inert liquids, and gases in high-temperature and high differential pressure applications. 
This valve family uses a stainless steel body with PTFE sealing and a semi-direct acting design, making it suitable for steam, hot water, condensate-related service, and other compatible media within rated limits.
Available sizes range from 1/2 inch to 2 inches with female NPT connections and a normally closed configuration. As a result, these valves fit buyers who need clear alignment on temperature, pressure, body material, seal material, and dimensional clearance before specifying for commercial or industrial equipment.

Pressure, Temperature, and Media Fit
These valves are designed for high-temperature service where steam, hot water, and compatible inert liquids or gases need a reliable electrically actuated shutoff. The valve operates from 0 psi minimum pressure and is listed for a maximum operating temperature of 356°F. In addition, maximum pressure varies by size and current type, with AC configurations listed up to 145 psi and DC configurations listed up to 90 psi on smaller sizes and up to 70 psi on larger sizes.
The file notes that the valve operates independently of pressure differential, so it can open and close even when inlet and outlet pressures are equal. It also recommends installing a downstream check valve to prevent back pressure and help maintain proper operation.
Dimensions and Size Range
Dimensional fit is important on steam lines, thermal equipment, and compact heated systems, so buyers should review the dimensional data before specifying for pipe clearance, actuator clearance, and service access. Specifically, this family is available in 1/2 inch to 2-inch female NPT sizes in a normally closed configuration.
