Product Description

1.1 Overview of high flow proportional solenoid valve
High flow proportional solenoid valve is Keyto independent research and development of a large orifice diaphragm solenoid valve, the main function is to control the flow of gas. Proportional valve control principle: pulse width modulation signal (PWM) control, by changing drive current of the coil to change the opening degree of the solenoid valve, so that there is a linear relationship between the current and solenoid valve flow. Proportional valve can take the way of open loop and closed loop control.

Typical Applications: Ventilators, Oxygenerator/Reservoirs, Anesthesia Delivery & Monitors, Pressure and Flow Control, Mass flow controller.
