Core Functions

Combined Electro-Hydraulic Control
The Electro-Hydraulic Directional & Proportional Control Valve combines a solenoid-operated pilot valve with a hydraulic main valve to control spool displacement, enabling precise hydraulic flow direction and proportional adjustment.

Large Flow Capacity
The electro-hydraulic proportional valve is designed for applications requiring high hydraulic flow. Based on Model DSHG-03, it supports a maximum pressure of 315 bar and a maximum flow rate of 200 L/min (52.8 gpm).

Stable Switching Performance
The optimized spool design reduces flow force during operation, improving switching stability and response performance. The five-groove valve body design supports high-pressure operation and back-pressure resistance.

Long Service Life
The valve has passed 10 million-cycle durability testing, helping ensure stable performance for long-term industrial applications.

Flexible Configuration
The valve can be equipped with a P-port pilot pressure cartridge and stroke adjustment device to improve operating characteristics and adapt to different hydraulic system requirements.

The performance data above are based on Model DSHG-03.

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.
