Key Takeaway
A proportional valve is usually located within hydraulic or pneumatic systems. It controls the flow or pressure of the fluid in a gradual manner. You can find it in systems that require precise control, like industrial machinery or automotive systems.
Check the equipment manual to locate it, as its position can vary depending on the system design. In simpler terms, a proportional valve acts like a dimmer switch for fluid flow. It’s often placed where precise adjustments are needed. If you’re looking for it, start by identifying the hydraulic or pneumatic lines in your system. Follow these lines, and you should spot the valve along the way. Manuals or system diagrams are your best guides.
