## Description

Allows automatic control of water or air flow in installations, closes at 12VDC power supply being normally open. Has 1/2 connection, metal plus plastic construction and diaphragm for low viscosity liquids. Works at pressures 0.02-0.8 MPa and withstands up to 100C, offering a good flow rate in common applications.
Electromagnetic valve (electrovalve) that allows the circuit to be closed when a voltage of 12VDC is applied with the help of a solenoid.
The model is Normally Open (when 12V voltage is applied, the valve closes).
It is not indicated for use in gravity fed systems.
