The Sun Hydraulics SCCALCE (SCCALCE) is a direct-acting sequence valve designed to manage hydraulic fluid flow in secondary circuits once the inlet port pressure exceeds the valve setting. This model features an integral check valve, enabling reverse flow from port 2 to port 1, with a pressure setting that controls the pressure at port 1 relative to the drain port 3. It's crucial for port 3 to be connected as it maintains a pressure reference in the control chamber; blocking it can lead to malfunction due to seal weepage. The valve can handle pressures up to 5000 psi (350 bar) and is suitable for load holding applications. The SCCALCE is part of a series where all three-port sequence cartridges are interchangeable, offering identical flow paths and cavity compatibility within a given frame size. This cartridge valve incorporates EPDM seals for use with phosphate ester fluids, avoiding petroleum-based fluids which could cause seal damage. For use in corrosive environments, corrosion-resistant options are available, identified by AP or LH suffixes for stainless steel or zinc-nickel plated components respectively. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variations. Key specifications include a capacity of 15 gpm (60 L/min), factory pressure settings established at 2 in\u00b3/min (30 cc/min), and maximum operating pressures of up to 5000 psi (350 bar). It features a typical response time of 2 ms and maximum valve leakage at reseat of 10 drops/min (.7 cc/min). The adjustment requires up to five clockwise turns with specific torque requirements for installation and locknut adjustments. With its robust design and versatile application capabilities, this model is an efficient solution for precise hydraulic control needs.
