Product Overview
The TOKYO KEIKI COM-5-33C-70-PN1-10 is a precision proportional directional and flow control valve engineered for advanced electro-hydraulic motion control in demanding industrial systems. Manufactured by TOKYO KEIKI (Tokyo Keiki Inc.), a globally recognized authority in fluid power and control instrumentation, this valve combines directional spool actuation with infinitely variable flow metering in a single compact body. The COM-5 series operates on a proportional solenoid principle, where an electrical command signal (typically 0–10 V or 4–20 mA) is converted into a proportional spool displacement, delivering smooth, repeatable, and load-independent control of both flow direction and magnitude. The “PN1” designation indicates a specific spool/spring configuration and rated pressure class, while the “10” suffix denotes the nominal flow capacity rating. This valve serves as a critical interface between electronic control systems (PLC, CNC, or dedicated amplifier cards) and hydraulic actuators such as cylinders and motors, enabling precise velocity profiling, position holding, and synchronized multi-axis movement without the complexity of servo-valve filtration requirements.
