Tokimec EPC-03-140-Y-11 Proportional Relief Valve

Description:

The Tokimec EPC-03-140-Y-11 Proportional Relief Valve is used in industrial hydraulic systems to provide electronically controlled hydraulic pressure regulation proportional to an input current signal. Commonly installed in hydraulic power units, CNC machine tools, injection molding machines, industrial presses, and automated manufacturing equipment. Maintenance teams and system integrators use this proportional relief valve for repair, retrofit, expansion, or replacement of electro-hydraulic pressure control systems.

Applications:

The Tokimec EPC-03-140-Y-11 Proportional Relief Valve is commonly used in hydraulic power units, metal forming machinery, injection molding equipment, material handling systems, test benches, and factory automation equipment where precise electronic pressure control is required. The EPC-03 Series allows hydraulic system pressure to be continuously adjusted through an external controller, making it suitable for closed-loop and PLC-controlled hydraulic applications.
