Proportional valve | Proportional valve symbol and working principle

Proportional valve symbol and working principle.

• In this valve the power supply to solenoid coil can be controlled by a regulator.It is same like conventional valve.In this valve the coil voltage can be very.
• In this valve the spool movement can be controlled.The spool can be moved as per our requirement.
• A amplifier is used to control this valve.It’s an open loop control.Large hysteresis (0.5%).
• USE – flow,direction and pressure control.
• Spools are overlapped.
• We can use LVDT(Linear variable Differential Transformer) for feed back of spool movement.

Benfits of Propertional Valve

• The operation of this valve is very smooth.
• It synchronize multiple actuator.
• Used for remote operation.
• Step less control.
