Core Functions

Hydraulic Pressure Protection
The valve controls system pressure by releasing excess hydraulic oil when pressure exceeds the preset value, helping protect pumps, actuators, and other hydraulic components.

Pilot-Operated Pressure Adjustment
The pilot control structure provides stable pressure regulation and supports different pressure adjustment ranges for various hydraulic applications.

Compact Modular Installation
The modular design does not require additional pipeline connections, helping reduce potential oil leakage points, installation costs, and required system space.

Stable Hydraulic Operation
The valve features low leakage, low vibration, and low noise characteristics, helping improve hydraulic system reliability and maintenance efficiency.

Multiple Configuration Options
The MBP series provides four structural designs and four pressure adjustment ranges. The MBP-02 model supports a maximum pressure of 250 bar and a maximum flow rate of 40 L/min (10.56 gpm).

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”.
