The SD6 and DLS7 represent state-of-the-art sectional valves, engineered for compactness, flexibility, and precision in control. Designed to cater to a diverse range of applications, these valves offer solutions tailored for small to medium hydraulic systems found in truck-mounted cranes, boom mowers, mini excavators, backhoe loaders, chipping machines, aerial platforms, and drilling rigs.
SD6: A Compact and Versatile Solution: The SD6 is characterized by its small size and flexible design, making it an ideal control valve for a variety of machinery. With a nominal flow rating of 45 l/min (12 US gpm) and a maximum pressure capacity of 315 bar (4600 psi), it is equipped to handle the demands of small and medium-sized hydraulic systems with efficiency and reliability. The SD6 can support up to 12 sections, allowing for extensive customization to meet the specific needs of each application.
DLS7: Optimized for Load-Sensing Applications: The DLS7 takes the functionality of the SD6 and enhances it for load-sensing applications, making it especially suitable for use on aerial platforms and in both vertical and horizontal drilling rigs. With a higher flow rating of 60 l/min (16 US gpm), the DLS7 is designed to provide more efficient control in systems where load variations are common, optimizing performance and energy use.
Advanced Features for Comprehensive Control:
Type "S" Free Flow Gallery: Ensures efficient fluid dynamics within the valve, promoting smooth operation and reducing pressure drops.
Integrated Safety Features: Both valves are fitted with a main pressure relief valve and a load check valve on every working section, ensuring stable operation and protecting the system from overpressure conditions.
Circuit Flexibility: Available with parallel, tandem, or series circuit configurations, these valves offer versatility to match any system requirements, enhancing functionality and adaptability.
Optional Carry-Over Port: Provides additional flexibility for hydraulic system design, allowing for the continuation of hydraulic flow to other sections or components.
Diverse Control Options: Accommodating manual, pneumatic, hydraulic, electro-hydraulic, and remote control with flexible cable, these valves ensure precise operation across various conditions and preferences.
Wide Range of Ports and Circuit Valves: The extensive selection of ports and circuit valves available with the SD6 and DLS7 valves allows for tailored hydraulic solutions, ensuring that each system can be optimized for its specific operational requirements.
In summary, the SD6 and DLS7 sectional valves offer unparalleled flexibility, efficiency, and precision for a wide array of hydraulic applications. Their compact design, combined with advanced features and extensive configurability, make them the ideal choice for professionals seeking reliable and versatile hydraulic control solutions.
