What’s a proportional valve
A proportional valve is a type of control valve that regulates flow rate or pressure continuously in proportion to an electrical input signal — rather than just switching fully on or off like a standard solenoid valve.
Here’s Ekgas a breakdown
How It Works
The valve receives an analog electrical signal (for example, 0–10 V or 4–20 mA).
The valve’s actuator moves the spool or plunger to a precise position that corresponds to the input signal.
This allows variable control of fluid (air, gas, or hydraulic oil) flow or pressure.
Main Types
Proportional flow control valves – adjust how much fluid passes through.
Proportional pressure control valves – maintain a set pressure that varies with the input signal.
Applications
Industrial automation – controlling actuator speed or force.
Hydraulics and pneumatics – smooth motion control.
Combustion systems – fine-tuning fuel and air ratios.
Process control – maintaining precise pressure or flow in manufacturing.
Advantages
Smooth and accurate control.
Can be integrated into automated systems.
Reduces wear and shock compared to on/off valves.
