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. Technical Data: Working voltage: DC4.5V Working mode: positive pulse opens the valve, negative pulse closes it. Pulse width: 30ms Current consumption: 0.4A Working pressure: 0.02-1Mpa Medium temperature: 1-80° Service life: 300,000 times Size: 5.5 x 5cm / 2.17 x 1.97in Weight: 130g Wiring method: red: "+", black: " -" For 1/2 inch threads. https://elecena.pl/product/22626316/1-2-pwm-controlled-high-precision-electric-valve-brass-angled 2023-02-23 https://elecena.pl/product/22626316/1-2-pwm-controlled-high-precision-electric-valve-brass-angled 2025-10-28
