Core Functions

Precise Manual Flow Adjustment
The Needle Valves feature an adjustable orifice that allows operators to regulate hydraulic oil flow according to system requirements. This helps achieve smooth actuator speed control and stable hydraulic performance.

High Pressure Capability
Designed for industrial hydraulic systems, the valve supports a maximum operating pressure of 250 bar, making it suitable for a wide range of hydraulic flow control applications.

Low Internal Leakage
The hydraulic cartridge needle valve uses a precision sealing structure with internal leakage of up to 3 drops per minute at 250 bar, helping maintain stable flow regulation and improve hydraulic efficiency.

Wide Operating Temperature Range
The adjustable orifice hydraulic valve operates within a temperature range of -30°C to +120°C, allowing reliable performance in various working environments.

Compact Cartridge Installation
The threaded cartridge design simplifies installation and maintenance while supporting hydraulic oil filtration of 20 μm or better to help reduce contamination and extend valve service life.

The performance data above are based on Model XNV-08.

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.
