The Sun Hydraulics SXCACDN (SXCACDN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve setting. This valve controls the pressure at port 1 relative to the pressure at drain port 3, and it is essential that port 3 remains connected to maintain a pressure reference in the control chamber. Blocking port 3 can lead to malfunction due to reciprocating seal weepage. The valve setting is directly influenced by the pressure at port 3 in a 1:1 ratio, not exceeding 5000 psi (350 bar). The SXCACDN is suitable for load-holding applications and is available with corrosion-resistant options identified by suffixes AP or LH for different external coatings. It incorporates Sun's floating style construction to reduce internal part binding due to installation torque variations. This sequence cartridge valve features physical and functional interchangeability with other three-port sequence cartridges of similar frame size, ensuring consistent flow paths and cavity compatibility. It has a capacity of up to 15 gpm (60 L/min) and operates under a maximum pressure of 5000 psi (350 bar). The response time is typically around 2 ms, and it exhibits minimal leakage at reseat, rated at approximately 10 drops/min (0.7 cc/min). The adjustment mechanism allows for up to four clockwise turns to increase settings, with specific hex sizes designated for various components such as the adjustment screw and locknut. The SXCACDN model weighs approximately .30 lb (0.15 kg) and requires specific installation torque parameters ranging from 30 - 35 lbf ft (41 - 47 Nm). A Viton seal kit is available under part number 990011006 for maintenance needs. This product's robust design makes it ideal for use in demanding environments where precise hydraulic control is necessary.
