Tokio Keiki TGMC-3-AT-FW-50 Modular Valve
The TGMC-3-AT-FW-50 is a specialized modular-type check valve manufactured by Tokio Keiki. Designed for integration into ISO 4401-03 (Cetop 3) hydraulic stacks, this valve provides a «pilot-to-open» check function specifically for the A-port. It is engineered to prevent oil from flowing back through the A-line unless a pilot signal is received, effectively locking a cylinder or actuator in place. This 50-series design is widely utilized in precision industrial machinery where load-holding and compact manifold architecture are primary requirements.

Fluid Compatibility: Standard mineral oil-based hydraulic fluids.
Key Features for Industrial Applications
Precision A-Port Locking
The TGMC-3-AT-FW-50 is specifically configured to control the A-line of the hydraulic circuit. In its de-energized state, the valve acts as a leak-proof seal, ensuring that the actuator remains stationary. When pilot pressure is applied from the designated pilot line, the internal poppet is lifted, allowing for controlled reverse flow and smooth movement of the hydraulic load.
Compact Modular Integration
By utilizing the modular stack (sandwich) design, the TGMC-3-AT-FW-50 eliminates the need for external plumbing. This reduces the risk of leakage and significantly simplifies the assembly of the hydraulic power unit. It is designed to be sandwiched between a subplate and a directional control valve, such as the DG4V-3 series.
