Vacuum applications include the electronics industry where partial removal of air is needed, vacuum manufacturing and automation systems, and vacuum pumps. A vacuum solenoid valve is usually designed to be leak-free, a necessary requirement in such conditions. They need no minimal pressure levels, which makes them best suited for these situations. Direct and semi-direct valve types are the most common.
Solenoid valves are widely used in vacuum applications.
Other automobile solenoid valves include the type used to shut off fuel flow and stop a vehicle, the type to drain water from a water fuel separator automatically, and the coolant control solenoid valve in a vehicle’s HVAC system. The fuel solenoid valve is common in countries that have regulatory rules for speed. It allows a medium to be controlled instead of shutting it off completely.Ī good example of this is when limiting the flow of fuel to the engine to reduce vehicle speed. In some of these functions, a variable solenoid valve is often utilized. They are usually used to regulate the flow of automotive fluids such as oil, anti-skid brake fluid or even fuel. With all these uses, these valve types are among the most common in the agriculture industry, perhaps only comparable to the pneumatic control valve.Ī range of solenoid valves are used in motor vehicle systems. Milking machines employ the action of an electromagnetic solenoid valve. You will also find these valves in equipment where they are used to dispense chemicals. Other uses include the transmission systems of farm machinery where they’re used to regulate different fluids. You will find them in irrigation devices such as the automatic sprinkler, or motorized farm machines to dose substances.Īn irrigation solenoid valve basically controls the flow of water and can be used to operate a sprinkler’s function autonomously. Most agricultural equipment contain solenoid valves to control a system.
