Tokio Keiki CPT-G06-1-50 Pilot Operated Check Valve
The CPT-G06-1-50 is a high-capacity, pilot-operated check valve engineered by Tokio Keiki. This right-angle type valve is designed for threaded connection mounting, allowing free flow in one direction and providing a dependable, leak-tight block in the reverse direction. The reverse flow is only permitted when external pilot pressure is applied to the internal piston, making it an essential component for hydraulic locking and load-holding applications where safety and precision are paramount.

Key Features for Industrial Applications
Advanced Hydraulic Locking
The CPT-G06-1-50 is primarily used to lock hydraulic cylinders in position, preventing drifting caused by directional valve spool leakage. Its poppet-style seat ensures an instantaneous, positive seal that maintains system pressure even during extended dwell periods.
Efficient Pilot Ratio
Designed for responsive operation, the internal pilot piston is optimized to open the main poppet with minimal pilot pressure relative to the load pressure. This efficiency reduces the energy required for decompression and switching, ensuring smooth transitions in the hydraulic circuit.
