Stainless Steel Steam Solenoid Valve – Normally Closed (IBR)
Stainless Steel Steam Solenoid Valve – Normally Closed (IBR) is a solenoid valve designed for steam and hot media lines, used with high-temperature diaphragm and seal materials. Its stainless steel body makes it the right choice for corrosive media and hygienic applications.

How Does It Work?
With the coil de-energised the valve is closed. When the coil is energised, the core is pulled up, the pilot orifice opens and the pressure difference lifts the diaphragm to let the medium flow. When power is removed, the valve closes.
Applications
- Steam lines
- Irons, presses and dryers
- Hot water lines
- Industrial laundries
Selection and Installation
Install the solenoid valve with the coil on top and fit a strainer upstream. For high temperatures, specify the diaphragm and seal material when ordering. Specify the coil voltage (AC/DC) when ordering. Send us your working pressure, temperature and application, and our technical team will recommend the right model and size.
