The Sun Hydraulics SCCACAE (SCCACAE) is a direct-acting sequence valve with an integrated reverse flow check feature, designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This model includes an integral check valve to facilitate reverse flow from port 2 to port 1. The pressure setting controls the pressure at port 1 relative to the drain port 3, and while it is a zero pilot flow valve, connecting port 3 is essential for maintaining a pressure reference in the control chamber. Blocking port 3 can lead to malfunction due to reciprocating 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). This valve is suitable for load holding applications and offers interchangeability in all three-port sequence cartridges, ensuring consistent flow paths across frame sizes. The SCCACAE model features corrosion-resistant options, identifiable by suffixes AP or LH for stainless steel or zinc-nickel plated components, respectively. It employs Sun's floating style construction to minimize internal part binding due to installation torque or cavity machining variations. With a capacity of 15 gpm (60 L/min) and factory pressure settings established at 2 in/min (30 cc/min), this valve operates at a maximum pressure of 5000 psi (350 bar) with typical response times of 2 ms. The valve leakage at reseat is minimal, measured at up to 10 drops/minute (0.7 cc/min), and features adjustable settings via clockwise turns. Additional specifications include a check cracking pressure of 40 psi (2.8 bar), and installation torque ranging from 30-35 lbf ft (41-47 Nm). The model weight is .30 lb (.15 kg), and it uses Viton seals with available seal kits for maintenance or replacement needs.
