The Sun Hydraulics SCCACAV (SCCACAV) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. This model includes an integral check valve that allows reverse flow from port 2 sequence to port 1 inlet. The sequence valve's pressure setting controls the pressure at port 1 relative to the drain port 3, and although it is a zero pilot flow valve, the drain must be connected to maintain proper function. Blocking port 3 can lead to malfunction due to seal weepage. The pressure at port 3 adds directly to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). Suitable for load holding applications, this cartridge is interchangeable with other three-port sequence cartridges of the same frame size, offering consistent flow paths and cavity compatibility. It features EPDM seals for systems using phosphate ester fluids, with corrosion-resistant options available for harsh environments identified by specific model code suffixes like AP or LH. The 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), maximum operating pressure of 5000 psi (350 bar), typical response time of 2 ms, and maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). The check cracking pressure is set at 40 psi (2.8 bar), with adjustment capabilities requiring up to five clockwise turns for increased settings. Installation requires specific torque values for both the valve and locknut components, ensuring secure placement without compromising performance integrity.
