【Pilot-operated Relief Valve DB20B Product Introduction】
The DB20B pilot-operated relief valve is a core component designed for hydraulic system pressure regulation, suitable for fluid control requirements in various industrial equipment and machinery. By integrating pilot valve and main valve mechanisms, this product achieves precise pressure adjustment and reliable system protection, featuring fast response, wide adjustment range, and stable operation to enhance overall hydraulic system performance.
With modular structure design and high-strength alloy steel construction, the valve ensures long-term durability under high-pressure conditions. Its key advantage lies in the rapid response to pressure fluctuations through pilot control circuits, which precisely limit maximum system pressure while minimizing energy loss. The multi-stage damping design optimizes pressure regulation characteristics, effectively reducing hydraulic shock and extending equipment service life.
This valve is widely applicable in hydraulic systems for construction machinery, metallurgical equipment, marine deck machinery, and other industrial fields, particularly suitable for scenarios requiring dynamic pressure compensation or frequent load variations. Offering multiple port connection options compatible with DIN standard hydraulic pipelines, it simplifies installation and maintenance. The adjustable pilot pressure setting mechanism enables continuous pressure regulation within 5-35MPa range to meet customized requirements.
Emphasizing environmental adaptability, the valve incorporates precision-machined flow channels and specialized surface treatments, demonstrating excellent contamination resistance and fluid compatibility with various media including mineral oil and water-glycol solutions. Compact dimensions and lightweight construction optimize space utilization for flexible equipment layout. Rigorous factory testing verifies outstanding performance in critical parameters such as pressure retention, sealing reliability, and operational repeatability.
