How A 2-Way Normally Closed Solenoid Valve WorksDESCRIPTION
How Does a 2-Way Normally Closed Solenoid Valve Work?
Some industries require the use of liquid or gas to complete a job, such as the medical and dentistry fields. Despite the differences in the fields that operate this type of equipment, the fact remains that the equipment needs to be able to start and stop liquid or gas as needed. That's where solenoid valves come into play.
Solenoid valves help to control the flow of liquid or gas. These valves are incorporated into the equipment so that the equipment can be used safely and efficiently. What a solenoid valve does is use a plunger to open or close the valve, either allowing the liquid to flow through or sealing it off without any leaks. This is an extremely important process in the automation of fluid and gas control, and there are different types of solenoid valves that does the same job in different ways.
The normally closed solenoid valve is one way to control the flow of liquid or gas. This valve is similar to other solenoid valves in that it either stops or starts the flow of the liquid, but it differs in the process it uses to do this. When a normally closed solenoid valve is not powered, the plunger is down, effectively sealing the valve and preventing the flow of liquid or gas. Once the normally closed solenoid valve is powered or energized, the magnetic field causes the plunger to rise. This unseals the valve and allows the flow of liquid or fluid to pass through.

2-way Normally Closed Solenoid Valves
A 2-way, normally closed, solenoid valve has 2 pipe connections, an inlet called the cavity port and an outlet called the body orifice port. When the valve is energized the plunger opens allowing media to flow through the valve in the cavity port and out the body orifice port.Turn off the power. The orifice closes and flow through the valve stops.
