Tokio Keiki TGMPC-3-ABK-51 Modular Valve
The TGMPC-3-ABK-51 is a high-performance, pilot-operated check valve in a modular «stack» configuration, manufactured by Tokio Keiki. Designed to meet the ISO 4401-03 interface standards, this valve is engineered for vertical stacking beneath a directional control valve. It provides a reliable hydraulic lock for both the A and B actuator ports, ensuring that the load is held firmly in position without drifting, even in the event of power loss or directional valve spool leakage.

Key Features for Industrial Applications
Reliable Load Holding
The primary function of the TGMPC-3-ABK-51 is to act as a hydraulic lock. By utilizing a pilot-to-open mechanism, the valve prevents flow from the actuator back to the tank unless pressure is applied to the opposite line. This is critical for safety in applications involving vertical loads, clamping mechanisms, or any system where unintended movement must be eliminated.
Smooth Decompression (K Type)
The «K» designation refers to the valve’s internal decompression feature. Before the main check valve opens, a smaller pilot poppet releases the trapped high pressure. This significantly reduces hydraulic shock (water hammer) and vibration, protecting the piping and components from fatigue and ensuring smoother machine operation.
