HOW SOLENOID VALVES WORK.

For water control, air applications and pneumatic processes they are used extensively in the Food Processing industry and anywhere that requires the easy and fast control of liquid or gas. They can be used for vacuum applications; we call these valves "Direct Acting" or "Zero rated", as they will work from zero pressure. The "Pilot operated" solenoid valves, on the other hand, use the media pressure to open and close the valve by the using a small electric magnetic field to pull a small piston up against a spring, thus revealing a "Pilot hole" in the diaphragm which causes it to lift under pressure from the media and allow passage through the solenoid valve. An "Assisted lift" type of solenoid valve has a spring attached to this small piston which lifts the diaphragm off it's seat thus causing the valve to open even if there is no pressure from the media, or in the presence of a vacuum. Connexion Developments in Bristol, UK (Tel 0800 808 7799) are the market leaders in this technology and are able to supply solenoid valves for all applications in Brass, Stainless steel, plastic, PTFE, Delrin, Bronze and other materials.
