The Sun Hydraulics SXCACBN (SXCACBN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This sequence valve controls pressure at port 1 relative to the pressure at drain port 3, and it is suitable for use in load holding applications. The SXCACBN model ensures functional interchangeability across all three-port sequence cartridges, sharing the same flow path and cavity for a given frame size. It incorporates Sun's floating style construction to minimize internal part binding caused by excessive installation torque or machining variations. The valve features a maximum operating pressure of 5000 psi (350 bar) and supports a capacity of 15 gpm (60 L/min). It is corrosion-resistant and compatible with corrosive environments, available with optional external stainless steel or zinc-nickel plated components. Notably, this zero pilot flow valve requires port 3 to be connected for maintaining pressure reference; blocking it may lead to malfunction due to reciprocating seal weepage. The pressure at port 3 directly adds to the valve setting at a 1:1 ratio and should not exceed the specified maximum. Additionally, the SXCACBN model offers quick response times of approximately 2 ms and minimal leakage at reseat levels of up to 10 drops/min (0.7 cc/min). Installation specifications include a torque range of 30-35 lbf ft (41-47 Nm) for valve installation, with adjustment capabilities provided through an internal hex screw requiring up to four clockwise turns for increasing settings.
