Core Functions

Proportional Flow and Direction Control
The valve uses proportional solenoid control to adjust spool position according to input signals, allowing smoother control of hydraulic actuator direction and speed.

High Flow Hydraulic Performance
The five-chamber design provides high flow capacity for industrial hydraulic applications. The valve supports a maximum flow rate of 35 L/min.

Fast Response and Low Hysteresis
The polished internal components help reduce hysteresis and improve response performance, supporting applications requiring accurate hydraulic movement control.

Long Service Life Design
The hardened spool and sleeve structure improves wear resistance and supports long-term operation in industrial environments.

Flexible Electrical Integration
The valve adopts a standard ISO 4401 G03 interface and supports connectors compliant with EN 175301-803, making it easier to match different amplifiers and control systems.

FAQ

1. What is a Proportional Solenoid Directional Control Valve used for?
A Proportional Solenoid Directional Control Valve is used to control hydraulic actuator direction and speed through proportional electrical signals, providing more precise movement control than standard solenoid valves.

2. What are the main advantages of a proportional directional control valve?
Key advantages include adjustable control, smooth actuator movement, fast response, and compatibility with electronic hydraulic control systems.

3. What pressure and flow requirements should be considered when selecting this valve?
Selection should consider system working pressure, required flow rate, hydraulic circuit design, control signal requirements, and actuator performance requirements.

4. What installation and electrical standards does this valve support?
The valve supports an ISO 4401 G03 mounting interface and EN 175301-803 compliant connectors for easier integration with hydraulic control systems.

5. How can I select the right Proportional Solenoid Directional Control Valve?
Provide your hydraulic system parameters, including pressure, flow rate, control requirements, and equipment application. Our technical team can help recommend a suitable valve configuration.

Ningbo Stars Hydraulic Co., Ltd.

Founded in 2001, Ningbo Stars Hydraulic Co., Ltd. is a hydraulic valve manufacturer that upholds integrity and wins market recognition through superior quality and pragmatic craftsmanship. We introduced hydraulic valve technologies from Germany’s Rexroth and Japan’s Yuken series, and through years of dedicated research, digestion, absorption, modification and optimization, our products stand out in the market. Our valves sell well nationwide and are exported to overseas markets, earning praise and trust from numerous customers at home and abroad. Though compact in size, hydraulic valves deliver critical functions as indispensable core components enabling multi-functional and automatic operation of mechanical equipment. The quality of a hydraulic valve largely determines the overall operating performance of the entire machinery. Supported by national industrial policies, China’s machinery industry is striving to catch up with European and American counterparts to meet booming demands from agriculture, industry, construction, transportation, and land, sea and air defense sectors—this momentum has greatly boosted the domestic hydraulic industry. To embrace the new wave of machinery upgrading, our company has launched a new round of optimization and improvement for our valve products. Building on our existing valve manufacturing technologies and processes, and under the guidance of domestic and international industry experts as well as Taiwanese technical engineers, we have comprehensively upgraded product structures, internal workshop purification and precision of core components. We have implemented effective control over internal stress, thermal deformation, leakage and noise of valves. Every batch of raw materials, auxiliary parts, semi-finished and finished products undergoes rigorous item-by-item inspection. We have also strengthened full-process quality supervision, with zero tolerance for defective products leaving the factory, guaranteeing reliable and long-lasting product performance. Our after-sales service includes timely technical guidance and warranty support, plus follow-up tracking of product operating conditions throughout their service life. Product competition is essentially a contest of technology, workforce dedication, team competence and corporate management. More importantly, it hinges on the founder’s philosophy, integrity and service mindset. There is no end to pursuing premium quality. Committed to specialization, refinement, quality excellence and technological innovation, our company adheres to the manufacturing principle of “Better fewer than shoddy goods” and the service tenet of “Put ourselves in customers’ shoes”.
