An explanation of solenoid valves and how they work

Solenoid Valves for process control and other applications come with the relevant approvals and certificates. You can learn much more about fluid and air control by visiting this site. Work out flow rates and pressures drops on page 145 of the solenoid valve catalogue. For help on all aspects of gas and liquid control, Food Process, LPG, Gas, Water control, Acid, Alkali, air applications, pneumatic process, Petrol and Diesel control valves in stainless steel, brass, plastic, nylon, Delrin and other materials in all sizes from 1/8" BSP solenoid valves to 12" Flanged. Just telephone your us or your account manager who is equipped to help you, a real person with expert knowledge

This catalogue is the only source in the UK for the world wide Shako Company Ltd, CS Fluid Power Ltd, Queen valves, Z-Tide, UNI-D, Era-Sib and many other valve Manufacturers. If you need a specialised valve for a special application this catalogue has it. If it doesn't have the answer there probably isn't one!

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. We 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 many other materials.
