DR10-30/31.5 Pilot-operated Pressure Reducing Valve
Product Overview:
The DR10-30/31.5 pilot-operated pressure reducing valve is a precision hydraulic control component designed for pressure regulation in industrial systems. Utilizing a two-stage pressure adjustment mechanism, it delivers stable secondary pressure output under complex operating conditions. With maximum inlet pressure capacity of 31.5MPa, its pilot control principle effectively reduces main spool driving force, making it suitable for systems with significant flow fluctuations. The modular compact design facilitates system integration, while surface hardening treatment enhances wear resistance of critical components.
Key Features:
- Precise pressure regulation: Independent pilot circuit ensures ±0.3MPa pressure deviation control
- Broad operational range: Compatible with mineral-based and synthetic hydraulic fluids at -20℃ to 80℃
- Dynamic responsiveness: Optimized damping structure achieves pressure stabilization within 1.5 seconds
- Enhanced sealing system: Triple-seal protection with imported elastomer materials prevents leakage
- Maintenance-friendly design: Standardized interfaces enable online servicing with replaceable core modules
Application Scope:
Widely implemented in construction machinery hydraulic controls, metallurgical equipment pressure maintenance systems, marine deck machinery power units, and mining equipment actuators. Typical applications include crane hoisting system stabilization, hydraulic press auxiliary circuit regulation, and injection molding machine clamping force control.
Usage Recommendations:
Install vertically at pressure branch points with 10μm pre-filtration. Perform no-load pressure preset during commissioning and conduct 500-hour pressure calibration during initial operation. Pilot ratio adjustment enables customized nonlinear pressure output characteristics for special applications.
