A Solenoid valve is an electromechanical valve for use with liquid or gas. The solenoid valve is controlled by an electrical current through a solenoid coil. Solenoid valves are used for many application processes most frequently for control elements in fluidics. The task of solenoid valves is to shut off, release, dose, distribute or mix fluids.
The Benefits of Solenoid Valves are:
- Fast and safe switching
- Highly reliable
- Long life service
- Good medium compatibility of materials used
- Low power control
- Compact design
The General Uses of Solenoid Valves:
- To control cylinders, fluid power motors or larger industrial valves in fluid pneumatic and hydraulic systems.
- Automatic irrigation sprinklers use solenoid valves with an automatic controller.
- To control water entry to and from processes
- Pharmacological experiments for application of agonist or antagonist
Solenoid Valves are a reliable and cost-effective method for controlling fuel in a range of combustion applications. A solenoid valve is a combination of two basic functional units:
- A solenoid (electromagnet) with its core. This provides the force to change the state of the valve.
- A valve body containing one or more orifices. This portion provides the pressure vessel and sealing to prevent leakage and control flow.
- Flow through an orifice is shut off or allowed by the movement of the core when the solenoid is energized or de-energized. The core is enclosed in a sealed tube, providing a compact, leak proof assembly.
Solenoid valves are made up of three basic types
- 2/2 solenoid valves which have one inlet and one outlet pipe connection. They are available in a normally open design for fuel gas venting purposes or a normally closed design for fuel gas and oil shut-off purposes
- 3/3 solenoid valves and 4/4 solenoid valves are used to divert flow or to drive a hydraulic or pneumatic actuator. They also can be used as a pilot for a large shutoff valve.
Solenoid valves are available in:
- 2/2 normally closed
- 2/2 normally open
- Manual reset
- 3/2 diversion
Solenoid valve operations handle the needs of
- Combustion system pilot control
- Main line fuel shutoff control
Features of solenoid valves include
- Junction box
- Pipe taps
- Visual indication
- Proof of closure
- Leading agency approval
- Pipe connections from 1/8” to 3”
Solenoid valves are available in
- Stainless steel
