Typical applications include machinery requiring fine-tuned control such as medical devices, industrial automation, and heavy machinery. The innovation behind these valves represents a significant leap in fluid control technology, making them indispensable in various sectors.

How Do Parker Proportional Valves Work?

The operation of Parker Proportional Valves is characterized by their ability to vary the flow rate based on an electronic input. This signal adjusts the valve's opening, controlling the amount of fluid passing through it. The core principle revolves around electromagnetism, where an electrical current induces movement in a coil. This movement translates into the mechanical action needed to modulate flow rates accurately and responsively. To delve deeper into their mechanism, Parker Proportional Valves typically consist of a solenoid coil, a spool or armature, and a spring mechanism, which together create a harmonious operational system.

When an electrical signal is applied to the solenoid coil, it generates a magnetic field that pulls the armature. This movement can either open or close the valve, depending on the design. The extent to which the armature travels is what determines the degree of the valve opening, thus allowing for infinitely variable flow rates rather than discrete on/off states.
