Ein normalerweise geöffnetes pneumatisches Solenoidventil ist eine Art von Ventil, die in seinem Standard- oder Normalzustand offen bleibt, aber geschlossen werden kann, wenn ein elektrisches Signal angewendet wird.
In a normally open (NO) configuration, the valve allows the flow of air or gas to pass through when there is no electrical power applied to the solenoid. When an electrical signal is supplied to the solenoid, it energizes and causes the valve to close, blocking the flow of air or gas.
The solenoid is an electromechanical device that consists of a coil of wire wound around a core. When an electric current flows through the coil, it generates a magnetic field that moves the core, activating the valve mechanism. By controlling the electrical signal to the solenoid, operators can open or close the valve remotely, providing a means of automation and control in pneumatic Systeme .
