Proportional Valves are the automatic controlling units that are used to change the output pressure and flow rate in the same ratio as per the pre-set ratio by altering the input. These can be simply connected directly to the flow channels to in various industrial applications. They are provided with a restrictor which can be controlled with the help of electrical unit. Proportional Valves also helps to adjust the parameters in a system such as mainly level, pressure, temperature, weight, thickness, humidity, density and viscosity. These are provided with a high performance solenoid coil which generates magnetic field due to electromagnetic induction.
