Working Principle
As a key control element of the hydraulic system, this CARTRIDGE VALVE is embedded into manifold block cavities. Pilot control oil acts on the top of poppet unit to control opening and closing of the main oil passage. By assembling different control covers, the Hydraulic valve can perform directional switching, pressure relief, pressure holding and unloading functions. The poppet hard‑seal structure effectively reduces internal leakage under high‑pressure condition. It delivers stable oil‑circuit control for cylinders and actuators of heavy‑duty Machine, ensuring reliable operation of the complete hydraulic system.
Core Advantages
1. Adopts international standard cavity dimension, TJ series CARTRIDGE VALVE possesses good interchangeability for manifold blocks of industrial Machine.
2. Large‑flow capacity with minor pressure drop, effectively cuts down heat generation and energy consumption of hydraulic system.
3. Poppet hard‑seal design achieves excellent pressure‑holding performance, minimal internal leakage during long‑time static pressure maintaining.
4. Highly flexible function configuration. Multiple hydraulic functions can be realized just by replacing control covers, which greatly simplifies loop design of hydraulic system.
5. Robust steel structure, adapts to continuous heavy‑load working environment, easy for disassembly, inspection and spare‑parts replacement.
