Product Overview
The TOKYO KEIKI TGMC-3-Y-PK-51 is a modular (sandwich-style) pressure control valve engineered for direct mounting between a directional control valve and its subplate or manifold in accordance with ISO 4401 / CETOP interface standards. As a pilot-operated relief valve within the TGMC series, it functions to limit maximum system pressure by diverting excess flow to the tank port once the adjustable set pressure is reached, thereby protecting downstream components from overpressure and enabling controlled pressure regulation in industrial hydraulic circuits. The “Y” designation indicates an internal pilot and external drain configuration, while the “PK” variant denotes the specific spring range and adjustment style. Manufactured by TOKYO KEIKI (Tokyo Keiki Inc.), a recognized Japanese producer of precision fluid power equipment, this valve is designed for stable pressure holding, low pressure override, and repeatable relief characteristics in continuous-duty hydraulic power units.

Engineering Features & Advantages
- Precision Pressure Control: Pilot-operated relief design delivers accurate, repeatable cracking and reseat characteristics with minimal pressure override, ensuring stable system pressure regulation across the full flow range.
- Modular Sandwich Construction: The Size 3 sandwich body mounts directly between a directional valve and subplate, eliminating external piping, reducing leak points, and simplifying system assembly and maintenance.
- External Drain Configuration: The “Y” internal-pilot / external-drain arrangement provides consistent relief performance independent of return line back pressure, ideal for circuits with restricted or pressurized tank lines.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with hardened internal components and a robust pilot stage for long service life.
- Direct Fit Replacement: Precision-manufactured to original TOKYO specifications for direct replacement, minimising downtime and eliminating fitment issues.
Typical Industrial Applications
As a pilot-operated relief valve within the TGMC series, it functions to limit maximum system pressure by diverting excess flow to the tank port once the adjustable set pressure is reached, thereby protecting downstream components from overpressure and enabling controlled pressure regulation in industrial hydraulic circuits.
