Iii. Product Features and Advantages
1. Core features
High-efficiency flow channel design: Internal flow channel optimization enables a large flow rate of 80L/min even when the pressure drop is ≤3bar, enhancing the system’s energy efficiency
Multi-valve core compatibility: It offers various valve core specifications such as C, D, and E, enabling functions like unloading, pressure holding, and bidirectional flow, and is suitable for complex hydraulic circuits
Reliable sealing structure: The integrated sealing design, combined with high-quality materials, has an extremely low risk of external leakage and nearly zero internal leakage, enhancing the system’s sealing performance
Compact and lightweight: NG06 specification, small in size and weighing only 2.5kg, saves installation space and meets the requirements of equipment miniaturization
Wide operating condition adaptability: With a wide temperature range of -25℃ to +70℃ and a high-pressure resistance capacity of 350bar, it is suitable for harsh industrial environments
2. Highlight the advantages
High reliability: The wet electromagnet has a protection grade of IP65 and strong anti-pollution ability. Spring reset ensures a return to the neutral position after power failure, with high safety redundancy and a service life of up to one million cycles
Convenient maintenance: The coil is modularly designed and can be replaced online without disassembling the oil pipe and valve body. The valve core is easy to disassemble, facilitating cleaning and maintenance
Low operating loss: The high-efficiency flow channel reduces pressure loss, and the low-power design of the electromagnet results in low long-term operating costs
Smooth reversing performance: Damping holes can be optionally equipped to achieve gentle switching. The reversing time is adjustable from 50 to 200ms, reducing the hydraulic shock protection system

Iv. Usage Functions and Purposes
1. Core usage functions
Directional control: Controls the flow direction of the hydraulic oil to achieve the switching of the actions of the actuating elements such as the extension and retraction of the cylinder and the forward and reverse rotation of the motor
System unloading: In the median state, port P is closed and ports A/B are open to Port T, achieving system unloading in non-working conditions and reducing energy consumption and heat generation
Pressure protection: By coordinating the valve core with the return oil port, pressure is released when the system is overloaded, preventing damage to pipelines and components
Sequential control: When used in conjunction with multi-valve groups, it controls the action sequence of multiple actuating elements through the on-off timing sequence to achieve an automated process
2. Main uses
As a core control component of the hydraulic system, it precisely controls the flow direction of hydraulic oil through electrical signals, connects the electrical control system with the hydraulic execution system, and drives the action control of mechanical devices. It is a key control node of the hydraulic system.
