Product Description

Pressure Sequence Valve Product Description

Pressure sequence valves are critical components for hydraulic circuit control, designed to automatically open and close according to preset system pressure values, ensuring that hydraulic actuators operate in a predetermined sequence. The DZ series pressure sequence valves, including DZ5DP, DZ6DP, DZ10DP and the specific model DZ6DP2 (R900513984, DZ6DP2-54/315YM), are engineered to deliver stable pressure regulation and reliable sequence control for heavy-duty industrial hydraulic systems.

Core Performance Features

Precise Pressure Setting & Control
The DZ6DP2-54/315YM pressure sequence valve is calibrated for a maximum working pressure of 315 bar, with accurate pressure adjustment that allows for precise matching of different hydraulic circuit requirements. Its internal pressure sensing mechanism ensures fast response to pressure changes, avoiding pressure shocks and ensuring smooth operation of the hydraulic system.
Strong Durability & Wear Resistance
Constructed with high-strength cast iron valve bodies and hardened steel internal spools, these valves can withstand harsh working environments with high pressure, high temperature and frequent load changes. The optimized sealing structure effectively prevents oil leakage, extending the service life of the valve and reducing maintenance frequency.
Flexible Installation & System Compatibility
The DZ series pressure sequence valves comply with international standard mounting interfaces, enabling direct integration into existing hydraulic circuits without additional modification. The compact design of DZ5DP and DZ6DP models is ideal for space-constrained equipment, while the DZ10DP model is suitable for large-flow hydraulic systems.
Wide Pressure Adjustment Range
With a flexible pressure adjustment design, the valves can be customized to meet different pressure requirements of various applications. The DZ6DP2-54/315YM variant supports precise pressure tuning within a wide range, making it adaptable to both low-pressure control scenarios and high-pressure heavy-load working conditions.

Application Scenarios

Construction Machinery: Controls the sequential operation of boom lifting, arm expansion and bucket tipping in excavators, loaders and cranes.
Industrial Hydraulic Equipment: Manages the sequence of clamping, feeding and processing in hydraulic presses, injection molding machines and metal forming equipment.
Metallurgical & Mining Machinery: Regulates the pressure sequence of conveyor belts, mine hoists and ore processing equipment to ensure safe and efficient operation.
Agricultural Machinery: Controls the hydraulic sequence of harvesting equipment, tractor attachments and irrigation systems for coordinated work.

Quality Assurance

Each DZ series pressure sequence valve undergoes strict factory testing, including pressure holding tests, leakage tests and performance calibration, to ensure full compliance with industrial quality standards. The robust structural design and high-quality components guarantee stable performance even under long-term continuous operation, reducing the overall operational cost of the hydraulic system for users.
