Tokio Keiki TGMFN-3-X-A2W-50 Modular Valve
The TGMFN-3-X-A2W-50 is a precision modular throttle check valve manufactured by Tokio Keiki. Designed for the ISO 4401-03 (Size 03) mounting interface, this valve provides high-accuracy flow regulation for the A-port of a hydraulic actuator. By integrating both the throttle and a bypass check valve into a single stackable block, it allows for adjustable speed control in one direction (Meter-in) while permitting free flow in the return direction. This 50-series valve is a staple in industrial hydraulics for fine-tuning the velocity of cylinders and motors.

Key Features for Industrial Applications
Precision Meter-In Control
The «X» configuration designates this valve for meter-in flow control. This means the valve regulates the volume of oil entering the A-port of the actuator. Meter-in control is ideal for applications where the load is resistive (pushing against a load), providing smooth and stable acceleration without the «lunging» effects sometimes associated with other control methods.
Secure Bolt-and-Lock Adjustment
The A2W adjustment style features a robust threaded bolt and a heavy-duty lock nut. This allows operators to set the desired actuator speed with high precision and then «lock» the setting in place. This mechanism is highly resistant to loosening caused by machine vibrations, ensuring that production cycles remain consistent over long periods.
