All valves that are actuated with an electromagnetic actuator and used during the process are designated into the category of process solenoid valves. They are often used in dosing applications because they have ultra-fast cycle duties.
- Water treatment plants, washing and cleaning installations
- Plants for the food and foodstuff industries, the chemical industry and electroplating
- Equipment for the photographic industry, laboratory, analytical and medical apparatus
In the case of solenoid valves, short-stroke globe valves are the valve type generally used. However, due to the limited force of the magnet, process solenoid valves are usually only used at low operating pressures. GEMÜ has therefore developed a patented double bellows system which compensates for pressure forces. As a result, the GEMÜ M75 process solenoid valve can be used across all nominal sizes, even at an operating pressure of 6 bar – all while using the same compact solenoid actuator. Watch the video to see how the pressure compensation works compared to conventional solenoid valves:
Pilot valves also have a solenoid actuator but are only used to actuate pneumatic actuators. GEMÜ also offers a wide range in this area. Take a look at the product overview
