Advantages
Real-time valve core position monitoring
Mechanical position is converted into electrical signals via sensors, enabling closed-loop control and preventing system failures caused by valve core jamming or malfunction. This is particularly suitable for applications with high safety requirements.
High dynamic response
Short valve core stroke and low inertia allow for millisecond-level switching times, making it suitable for hydraulic circuits requiring rapid start/stop or frequent reversals, significantly improving system efficiency.
Compact structure and high integration
Compared to traditional plate valves, the size is reduced by more than 50%, facilitating complex functional combinations within an integrated block, reducing piping connections and leakage points, and optimizing equipment layout.
Excellent sealing performance
Utilizing a conical or arc-shaped sealing structure, leakage is extremely low (typically<5ml/min), maintaining pressure for extended periods without loss, suitable for processes with strict pressure holding requirements.
High pressure and high flow capacity
Stable operation at a maximum pressure of 420bar, meeting the power transmission needs of heavy equipment, with minimal pressure loss and significant energy savings.
Modular design for easy maintenance
When the valve core wears, the entire valve block can be replaced without disassembling it, reducing maintenance time by over 70% and lowering downtime costs.
High reliability of electromagnetic drive
Utilizing a wet electromagnet design, it is dustproof and waterproof, with a lifespan exceeding ten million cycles; 24V low-voltage control ensures greater safety and allows direct connection to a PLC control system for digital management.
Application Areas
Metal Forming Machine Tools
During the slider synchronization control and pressure holding stages, valve core position monitoring ensures multi-cylinder movement accuracy of ±0.1mm; high pressure capacity meets the requirements of thick plate forming, and sealing performance guarantees pressure holding time of up to tens of seconds without pressure leakage.
Plastic Injection Molding Machines
Rapid speed and pressure switching is required during injection, and the dynamic response of the valve directly affects the product molding cycle. Real-time monitoring can provide early warning of valve core wear, avoiding quality problems such as flash and short shots, thus improving yield.
Metallurgical Equipment
In high-temperature and dusty environments, the closed structure of cartridge valves prevents impurities from entering; the 420 bar pressure rating meets the high thrust requirements of the rolling mill's AGC hydraulic cylinders; position monitoring is linked with the HMI system for remote fault diagnosis.
Construction Machinery
The integrated block structure adapts to the space constraints of mobile equipment; rapid reversing characteristics optimize the coordination of boom and stick composite movements; the electromagnetic drive has strong vibration and shock resistance, conforming to the ISO16750 road vehicle standard.
Marine and Marine Engineering
The compact structure facilitates cabin space utilization; the wet electromagnet is resistant to high humidity and salt spray corrosion; the valve core position signal can be integrated with the ship's central control system, meeting the automation requirements of unmanned aerial vehicle (UAV) cabins.
Press machines and automated stamping lines
Single stamping cycle<2 seconds, relying on rapid valve switching; safety regulations require monitoring the actual status of the valve core to ensure that the slide can reliably lock in case of emergency stop, preventing accidental downward movement and workplace injuries.
