How Small Pressure Relief Solenoid Valves Work
Have you ever wondered how small pressure relief solenoid valves work? These important devices are used in several different modern day inventions that we probably all take for granted, from washing machines to coffee makers. This article will explain the basics of how they work, as well as some information on the very similar hydraulic solenoid valves.
A solenoid coil is the main functioning part of these small pressure relief solenoid valves and they are controlled by electric currents. They are in essence a form of electric tap that opens the valve and allows water to flow when you need it. The small coils and cylinders in these machines are strong enough to keep the water from flowing when the machine is not turned on. This is accomplished by using the pressure of the water itself to stop the water from coming out.
The small pressure relief solenoid valves uses a steel piston that is attracted by the magnetism of the solenoid coil and pulled in when you turn on the electric current. The piston rests on a seal, typically a rubber disc. This disc has two small holes, one of which on the side allows water to enter; the water pressure itself keeps the water in. When the current is turned on, the piston is removed from the hole in the center. This lowers the pressure within, which in turn allows water to pass through.
Probably the most well known and widely used small pressure relief solenoid valves are the Asco solenoid valves. Their company is the world leader when it comes to supplying these products as well as other valve technology. They offer micro miniature solenoids that can be used in a wide variety of applications as well as several other products including sensors, pneumatic controls, and position indication technology. Because they are such a trusted and longstanding company, there is little risk in purchasing their products which can be found in most home improvement stores as well as on the Web.
Hydraulic solenoid valves work on a very similar principle, as they too use solenoids in order to function. These devices are typically used in pilot circuits where they control several different control valves and variable displacement pumps. They are well known for their conveniently small size and how easy they are to use. This makes them highly reliable and ideal for use in aerospace, marine, and defense applications.
There are currently several different variations to choose from, such as wet and dry solenoids. Even in hostile environments you can count on them. These hydraulic solenoid valves may be powered by either one or two solenoids. You have different power ratings to choose from and some models even come with indicator lights. When you need something that is not too expensive and also easy to install, you couldn’t make a better choice.
