SUN Series Pioneering Pressure Relief Overflow Valves: Safeguard Your Hydraulic Systems with Precision

Core Advantages: Engineered for Reliability & Performance

Ultra-Precise Pressure Regulation

Each valve is calibrated with meticulous precision to respond instantly to pressure fluctuations. It maintains a steady system pressure range, preventing overpressure damage to pumps, pipelines, and other hydraulic components while minimizing energy waste. This precision is critical for both heavy-duty industrial operations and high-precision hydraulic applications.

Robust & Long-Lasting Build

Crafted from high-strength, wear-resistant industrial alloys, the SUN Series valves excel in harsh operating environments—from high-temperature manufacturing plants to rugged construction machinery hydraulic systems. The corrosion-resistant coating and sealed internal structure ensure resistance to contamination, extending service life and reducing maintenance frequency.

Fast Response & Low Leakage

The advanced valve core design enables rapid opening and closing, effectively relieving excess pressure in milliseconds to avoid system shock. Meanwhile, the precision-machined sealing components ensure minimal internal leakage, enhancing overall system efficiency and reducing fluid loss.

Versatile Compatibility & Easy Integration

Designed with universal mounting dimensions, the SUN Series valves seamlessly integrate with most standard hydraulic systems, eliminating the need for complex modifications during installation. Whether for retrofitting existing equipment or outfitting new systems, these valves offer hassle-free deployment.
