Proportional Valves Manufacturers

Proportional Valve is an economical proportional valve for use with gases. It combines a solenoid valve with an electronics package, which digitally modulates the control signal to provide analog proportional control without the expense or complexity of stepper motors, servo valves or other proportioning devices. It can be used in open or closed loop systems to control flow, pressure, temperature, speed or position parameters of gases. There are two types of proportional valves force controlled and stroke controlled. With a force controlled proportional valve, a provision is provided to increase the force output by the solenoid proportional to the input signal. Both types provide an opening of the valve proportional to the magnitude of the milliamp current applied to the valve. Spool movement is proportional to the input current.
