Standard Valve Packages: Sun has developed a selection of assemblies incorporating commonly used hydraulic functions. These assemblies typically include two or more different cartridges integrated into a variety of mounting options. A single part number is built during the option selection process allowing for convenient ordering.
Sun Hydraulics manufactures custom engineered valve packages or "valvepaks" at all of its locations around the world. Valvepaks are comprised of standard screw-in cartridge valves housed in a custom manifold. Once a customer's hydraulic circuit has been developed, it is incorporated into a single, custom manifold designed to fit into a defined location. Benefits to customers using Sun's valvepak solutions include order simplification, reduced assembly time, and cost, and consolidation of the hydraulic control system.
All of our facilities use similar processes to design and manufacture custom valvepaks that are backed by Sun's full range of screw-in hydraulic cartridge valves. All manifolds can be manufactured in either T-6061 aluminum (3000 psi/210 bar) or 65-45-12 high-strength ductile iron (5000 psi/350 bar).
The beauty of Sun's valvepak solutions are that they all use our field proven, standard cartridge valve components with floating construction. Because of the inherent reliability of our cartridge valves, custom valvepaks typically do not require expensive, sophisticated testing once assembled.
Once a circuit has been developed, the valvepak design process starts. Sun's process is different than most other custom manifold suppliers due, in part, to our extensive use of compound angle drilling. We can locate ports, mounting surfaces and holes, and cartridges just where you need them. The true benefit though, is Sun's valvepaks are generally smaller in size with fewer potential leakage points and construction drillings.
Custom valvepaks can range from relatively simple manifolds with two or three cartridges, to highly complex manifolds containing 20, 30 or more individual cartridge valves! And you don't need a requirement of 500 pieces to justify a custom valvepak. With our design and manufacturing approach, we are able to provide minimum quantity packages at very competitive prices.
