Proportional Controller

Proportional Controller

A proportional controller amplifies the input command signal into an output current that drives the proportional valve. Our controller, based on a digital microprocessor, features a physical screen and buttons for easy setup. Currently, we offer both PCB-only, Plastic Case and DIN43650 plug types. Each type includes short and open circuit protection with error codes to ensure safety.
Solenoid-Operated Valves

Solenoid-Operated Valves

A solenoid-operated valve is an electromechanically operated binary valve acting in on/off mode. Solenoid-operated valves distinguish themselves from pilot-operated and manually adjusted valves by utilizing electrical control instead of complex mechanical linkages or bulky hydraulic pilot lines. Compared to traditional methods, solenoid-operated valves offer simpler circuit design and easier installation.

The cavities of our solenoid-operated valves are identical to those of non-solenoid cartridge valves, ensuring smooth implementation and resulting in cost savings as an added benefit.
Electro-Proportional Valves

Electro-Proportional Valves

Electro-Proportional valves are actually a type of solenoid valve. Electro-proportional valves offer continuous control in applications where output flow or pressure varies. With an additional amplifier controller, the output of these valves becomes proportional to the input command signal, enabling more precise and accurate control. Similar to solenoid-operated valves, the cavities of proportional valves are identical to those of our non-solenoid cartridge valves.
