## Description

12VDC solenoid valve for water or air, normally closed, opens when voltage is applied, ideal for automation and flow control in pressure installations. 1/2 connection, metal and plastic body, operates up to 0.8MPa and 100C, diaphragm type for low viscosity liquids.
Electromagnetic valve that allows the circuit to open when a 12VDC voltage is applied using a solenoid.
The model is Normally Closed (opens when 12V voltage is applied).
It is not recommended for use in gravity feed systems.
Important: A resistor and capacitor circuit is recommended to prevent the solenoid valve from overheating. It requires a higher current only during the solenoid actuation phase, and then consumes a much lower current to maintain it. Prolonged use with a high current will lead to overheating and failure of the solenoid valve, which is not covered by the warranty!
