Tokio Keiki EPFG-03-125-N-10 Proportional Valve
The EPFG-03-125-N-10 is a high-precision, solenoid-operated proportional flow control valve manufactured by Tokio Keiki. This valve is designed to provide accurate, remote-controlled regulation of hydraulic fluid flow, regardless of fluctuations in load pressure. By combining a proportional solenoid with a pressure-compensating mechanism, the EPFG series ensures stable actuator speeds, making it an essential component for automated industrial machinery, synchronized lifting systems, and precision injection molding applications.

Key Features for Industrial Applications
Load-Independent Flow Regulation
The primary advantage of the EPFG-03-125-N-10 is its integrated pressure compensator. This feature ensures that the flow rate remains constant even if the pressure drop across the valve changes due to varying loads on the actuator. This leads to superior machine precision and prevents «speed surge» when resistance changes during a work cycle.
High-Resolution Proportional Control
Equipped with a high-performance proportional solenoid, this valve translates electrical input signals into linear flow output. This allows for smooth acceleration and deceleration (ramping) of hydraulic cylinders and motors, reducing mechanical shock and increasing the overall lifespan of the machine’s structural components.
