DA-30 Pilot-operated Relief Valve Product Introduction (English Version)
The DA-30 series pilot-operated relief valve is an advanced pressure control solution engineered for industrial hydraulic systems, delivering reliable pressure regulation and overload protection across diverse operating conditions. Utilizing a pilot-controlled mechanism, this valve achieves precise main spool modulation, enabling rapid response within preset pressure thresholds to maintain system stability during dynamic load changes.
Featuring a modular construction crafted from high-strength alloy materials, the valve incorporates optimized internal flow channels that minimize pressure drop. Its key performance attributes include sensitive actuation characteristics and a broad adjustable pressure range spanning 10-350bar, allowing flexible customization for specific application requirements. The multi-layer anti-corrosion surface treatment enhances durability in challenging environments with high humidity or particulate contamination. Specially engineered sealing assemblies effectively prevent internal leakage, ensuring consistent pressure control accuracy throughout extended service periods.
This valve finds extensive application in construction machinery, metallurgical equipment, marine hydraulic systems, and other scenarios requiring periodic pressure relief. In typical applications such as injection molding machine clamping systems, forging press hydraulic stations, and mining equipment power units, its integrated damping mechanism reduces pressure fluctuations by approximately 40% compared to conventional designs, contributing to smoother system operation. The service-friendly design incorporates removable filtration elements for simplified maintenance, effectively reducing lifecycle costs.
Available with multiple port configurations (including ISO metric threads and flange connections), the DA-30 adapts to various piping dimensions. Each unit undergoes rigorous quality verification processes, including 72-hour endurance testing and 50,000-cycle operational validation, ensuring industrial-grade reliability. Comprehensive technical support services are available, including customized parameter adjustments and system integration consulting to optimize hydraulic circuit configurations for specific operational requirements.
