2WH Brass Normally Open Solenoid Valve

2W normally open solenoid valve is 2 way position semi direct acting diaphragm electric water solenoid valve. The valve is closed when the solenoid coil of de-energized(power off).  If the solenoid valve is required long-term opening, the normally open solenoid valve will be the ideal choice.

Water solenoid valves are very important to the automation of water or others fluid control, it;s vital that the right solenoid valve be used for a certain function. One commonly used solenoid valve is one that is normally open. This valve works slightly different than a valve that is normally closed.

The basic function of the normally open solenoid valve is the same. A normally open solenoid valve controls the flow of gas or liquid. This valve differs in the way that the flow is started or stopped. When a normally open solenoid valve is de-energized, the plunger is down, which means that a flow is allowed through the valve. Once the coil on the plunger is energized, however, the magnetic field causes the plunger to rise. This effectively seals the valve, preventing the gas or liquid from flowing through.
