The Sun Hydraulics WRL (Material Number: WRL) is a sandwich manifold designed with an ISO 07 interface and features on A to T, port 3 to B. The manifold has a stack height of 2.74 inches (70 mm) and accommodates open cavities with a T-17A cavity type. It is equipped with 1/4 BSPP port sizes, making it compatible with various hydraulic configurations. This manifold body is used in hydraulic systems where modular stacking of directional control valves is required, allowing for compact system design and efficient fluid flow management. The WRL model's unique design ensures easy integration into existing systems while maintaining optimal performance in controlling fluid direction and pressure within the circuit. Its construction from 6061-T651 aluminum provides excellent corrosion resistance and strength, suitable for environments where these factors are critical. Additionally, the sandwich manifold's design includes specific boss profiles, which facilitate consistent alignment during assembly and contribute to its aesthetically pleasing appearance when stacked with other manifolds. This model does not require anodizing due to the inherent properties of the aluminum used, which supports its durability without additional surface treatment processes that could impact fatigue life or increase costs. When assembling a stack of sandwich valves using this manifold, it is crucial to maintain dry o-ring sealing surfaces to prevent hydraulic fluid leakage through the pressurized port interfaces.
