TGMPC Series Sandwich Pilot Operated Check Valves

Product Overview: The TGMPC series is a high-performance sandwich plate pilot-operated check valve, commonly referred to as a “Hydraulic Lock.” Designed to ISO standards, it mounts directly beneath a directional valve to ensure the precise positional locking of actuators (cylinders or motors), effectively preventing load drift caused by spool leakage. Available in Size 3 (NG6) and Size 5 (NG10), the TGMPC series is renowned for its zero-leakage sealing and rugged cast-iron construction, making it a staple in injection molding machines, small presses, and automated clamping circuits.

Featured models: TGMPC-3-ABK-BAK-51, TGMPC-5-DABK-DBAK-50, and TGMPC-3-DABK-DBAK-51.

Key Technical Advantages:

• Zero-Leakage Sealing: Features a precision poppet design that ensures no fluid seepage in the locked state, guaranteeing load safety during long-term pressure holding.

• Compact Sandwich Design: The modular format eliminates external piping, stacking directly between the subplate and directional valve to minimize manifold volume and potential leak points.

• Independent Dual Control: Models with ABK-BAK or DABK-DBAK suffixes provide independent pilot-operated locking for both A and B ports, offering comprehensive actuator protection.

• Optimized Pilot Ratios: Expertly engineered cracking pressures ensure smooth, vibration-free opening across a wide range of system pressures.
