FAQs about Working Principle of Solar Zero Pressure Solenoid Valve
How does a direct-acting solenoid valve work?
The direct-acting solenoid valve is generally used with small flow-rate applications. The working principle of a direct-acting solenoid valve is, When there is power at the electrical coil it generates an electromagnetic field and attracts the plunger to the upward side. This will open the orifice and allows the media to flow through it.
How does a pilot-operated solenoid valve function?
A pilot-operated solenoid valve functions as follows: When the power is cut off, the electromagnetic force disappears and the spring presses the closure member on the valve seat to close the valve.
