The Sun Hydraulics SCCACDV (SCCACDV) is a direct-acting sequence valve with an integrated reverse flow check, designed to supply a secondary circuit with flow once the inlet port 1 pressure exceeds the valve setting. This model features an integral check valve that allows reverse flow from port 2 back to port 1. The sequence valve controls pressure at port 1 relative to the drain port 3, which is essential for maintaining a pressure reference in the control chamber. The valve setting is directly additive to the pressure at port 3 in a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). It is suitable for load holding applications and offers functional interchangeability among all three-port sequence cartridges of the same frame size. The SCCACDV model incorporates Sun's floating style construction to minimize internal binding due to excessive torque or machining variations. This cartridge valve has a capacity of 15 gpm (60 L/min) and operates effectively under pressures up to 5000 psi (350 bar). It provides rapid response times, typically around 2 milliseconds, and maintains minimal leakage rates at reseat conditions. The check cracking pressure is set at 40 psi (2.8 bar), and adjustments can be made via clockwise turns of up to five and a half turns. Installation specifications include a hex size of 7/8 inch (22.2 mm) and an installation torque range between 30-35 lbf-ft (41-47 Nm). The model weighs approximately .30 lb (.15 kg), and it supports configurations with EPDM seals for systems using phosphate ester fluids while offering corrosion-resistant options identified by specific model code suffixes such as AP or LH for external component finishes.
