Stainless Steel Solenoid Valves
Showing all 11 results
Stainless steel solenoid valves are chosen for corrosive media and hygienic applications thanks to their stainless steel body. The Unox stainless range covers general purpose (IGM), compressor (IKM), steam (IBR) and block body (PSV) models, with normally closed, normally open, 3/2-way and high-pressure options.

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.
With the coil de-energised the valve is open and the medium flows freely. When the coil is energised the valve closes; when power is removed it opens again.
A 3/2-way valve has three ports. De-energised, the inlet is closed and the outlet is open to exhaust; energised, the inlet is connected to the outlet. It is used to control pneumatic cylinders and actuators.
Applications
- Water and irrigation lines
- Compressed air
- Neutral gases
- Light oils and liquids
- Machinery and automation
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.
