Definition of a Valve or what is a valve

NormallyOpen Valves. An example of a normallyopen actuated valve is PlastOMatic's Series EASYNO Solenoid Valve. The valve closes when energized, and when that current is turned off, an isolated spring inside the valve forces it open. The magnetic force of the solenoid coil must overcome the force of the spring to close the valve.
