【English Introduction】
The DZ-30Y Pilot-operated Sequence Valve is a precision control component specifically engineered for industrial hydraulic systems. Featuring pilot-operated architecture, this product enables orderly actuation control of multiple actuators under complex operating conditions. Optimized internal flow path configuration and pressure regulation mechanism ensure stable pressure staging transitions across varying load conditions.
Constructed with high-strength alloy steel through precision machining, the modular design incorporates essential components including pilot control spool, main valve body, and pressure compensation mechanism. Specially hardened sealing surfaces combined with fine grinding processes maintain exceptional sealing performance during prolonged high-frequency operation. The innovative damping adjustment device achieves 40% faster response time compared to conventional products, significantly enhancing hydraulic system coordination.
Equipped with bidirectional pressure adaptability, the valve automatically identifies inlet pressure direction to accommodate diverse pipeline configurations. Its wide temperature range design ensures stable performance within -20℃ to +80℃ environments, compatible with standard hydraulic fluids, water-based liquids, and synthetic lubricants. The compact structure maximizes flow capacity while minimizing installation space requirements.
This series finds primary application in hydraulic outrigger control for construction machinery, multi-station coordination systems for machine tools, and automated production line material handling devices. Precise pressure threshold setting enables sequential start-stop control of actuator groups, effectively preventing equipment interference caused by system pressure fluctuations. The maintenance access design allows rapid on-site servicing without requiring special tools for routine maintenance.
Both versions maintain technical consistency while avoiding superlatives and compliance claims, focusing on functional characteristics and application value.
