The 3-way switching valve was driven by a stepper motor to switch the inside rotor to a specific port, but it is was triggered by DC7-33V voltage signals to power on and off just like common solenoid valves. Regarding this high pressure water solenoid valve, we have 2 way, 3 way, 4-way valves available, all these models anti maximum pressure to 1.6Mpa which can be used in special pressure systems. Runze is a professional switching valve manufacturer and supplier, we are able to offer various fluid control equipment. If you want to know more, please contact us now!
