The Sun Hydraulics A7B (Material Number: A7B) is a specialized manifold designed for use with solenoid-operated and electroproportional cartridges. This manifold features additional material around the cavity to ensure adequate coil clearance and includes the necessary spotface for Sun's weatherized coil. It is a line mount body type with no specific interface, and it incorporates a ninety-degree configuration with a reverse flow check, allowing it to accept both standard and weatherized coils. The manifold has 22 mounting holes, each with a diameter of 0.34 inches (8.6 mm), and they extend through the body. It contains 11 open cavities that conform to the T11A cavity specification, making it compatible with various cartridge designs. Additionally, the port size is specified as 38 NPTF. This product is constructed from 6061T651 aluminum, known for its strength, cost-effectiveness, machinability, availability in diverse shapes and sizes, and excellent corrosion resistance. The decision against anodizing these aluminum bodies stems from factors such as cost implications, logistical challenges in mass production consistency, potential inspection difficulties due to color changes affecting visibility of burrs or defects, increased breakaway torque upon item removal from an anodized surface, and notably reduced fatigue life due to the brittle nature of anodized surfaces under pressure. The A7B manifold's design makes it suitable for applications requiring robust hydraulic control solutions where environmental factors necessitate weather-resistant components. Its compatibility with both standard and weatherized coils broadens its applicability across various operational settings where reliability in hydraulic system performance is critical.
