Sun Hydraulics Type DBAL Valve | DBALXHN DBALS DBALSHN | 3-Way Solenoid Spool Valve | T-9A Cavity

Sun Type DBAL Series Pilot-Operated 3-Way Solenoid Directional Spool Valves

Product Overview: The DBAL Series is a pilot-operated, screw-in cartridge 3-way solenoid directional spool valve designed for the standard T-9A cavity. These valves utilize a solenoid-controlled pilot stage to actuate the main spool, making them ideal for actuator reversal, multi-level pressure selection, and pilot circuit switching within integrated hydraulic manifolds.

This category features essential configurations, including the standard DBALXHN, the manual override version DBALS, and the high-performance manual-equipped DBALSHN. Its compact cartridge architecture offers maximum flexibility for hydraulic circuit design.

Key Technical Advantages:

• Precision Pilot Operation: The pilot-operated design ensures smooth and accurate switching even under high-pressure conditions, reducing direct reliance on solenoid force.

• T-9A Cavity Compatibility: Strictly adheres to the Sun Hydraulics T-9A interface standard, enabling seamless replacement and upgrades for existing manifold systems.

• Versatile Manual Options: Available with manual override buttons (e.g., DBALS) to ensure emergency operation and system testing during electrical power failures.

• High Pressure Endurance: Precision-machined from high-strength steel, these valves handle operating pressures up to 350 Bar with exceptional reliability.
