G3/4" DN20 NC - Pressure Inlet Solenoid Valve - 0.02~0.8 MPA - Normally Closed

A solenoid pressure valve, also called inlet valve, is a type of electric valve where a solenoid allows water to open the valve for it can flow under its own pressure. Imagine solenoid as a semaphore saying "I am opening the valve lock, now press hard to open it, keep pressing and flow until I close the lock again". This type of valve is usually mounted on water supply lines and simply works as an electric tap.

As a contrary, valves may require no flow pressure to work. Those are called non-pressure valves, drain valves or outlet valves. Drain valve opened allows free flow of water regardless its pressure. A good example of an outlet valve use case is to empty an open (non-pressurized) tank. The drain valve, installed at the bottom outlet of the tank, allows to drain the tank and it is gravity that forces the water flow.

Solenoid valves may be NC - normally closed or NO - normally open. An NC valve remains locked as long as there is no current flowing through the solenoid. Once you power the solenoid, it unlocks the valve so water may flow. NO valve is the opposite - powering the solenoid locks the valve and cutting power allows water flow.

Our series of solenoid valves includes 220V AC, 24V DC and 12V DC solenoids in both NC and NO configurations and for various inlet/outlet threads, like G1/2 or G3/4 and are best choice for your Arduino projects when you want to control water flow with a microcontroller like Uno or Raspberry PI. A standard relay is everything else you need.
