The Sun Hydraulics SXCAKAV (SXCAKAV) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This valve is particularly notable for its ability to control pressure at port 1 relative to the pressure at drain port 3, making it suitable for load holding applications. It features a zero pilot flow design, which requires that port 3 be connected to maintain a pressure reference in the control chamber; blocking port 3 can lead to malfunction due to reciprocating seal weepage. The maximum allowable pressure at port 3 is additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). The SXCAKAV model incorporates Sun's floating style construction, minimizing internal parts binding due to excessive installation torque or cavity/cartridge machining variations. It has a cavity size of T-11A, series 1, and offers a capacity of up to 15 gpm (60 L/min). Factory pressure settings are established at 2 in/min (30 cc/min), with a maximum operating pressure of up to 5000 psi (350 bar) and typical response time of around 2 ms. The maximum valve leakage at reseat is minimal, recorded at only 10 drops/min (0.7 cc/min). For adjustments, it requires approximately four clockwise turns to increase settings, and it includes specific hex sizes for both the adjustment screw and locknut. Additionally, the model supports corrosion-resistant options for use in challenging environments and weighs approximately .30 lb (.15 kg).
