1/2" PWM-Controlled High-Precision Electric Valve - Brass - Straight

A high-quality brass PWM-controlled one-way electro-valve for 1/2" threads on both inlet and outlet.

WARNING: 

This valve is controlled with PWM signal, what allows to control the flow of liquid with a very high accuracy. Applying constant, direct voltage to the valve will not change its position - this is not a standard solenoid valve.
