The Sun Hydraulics SCEACAV (Material Number: SCEACAV) is a direct-acting sequence valve with an integrated reverse flow check. This valve is designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the pre-set valve threshold. It features an integral check valve that facilitates reverse flow from port 2 to port 1, ensuring efficient operation in load-holding applications. The pressure setting of this sequence valve regulates the pressure at port 1 relative to the drain port 3, which must be connected to maintain proper function; blocking it can lead to malfunctions due to reciprocating seal weepage. The valve's pressure capacity is substantial, accommodating up to 5000 psi (350 bar), and it is suitable for use in systems requiring robust performance under high pressures. This sequence cartridge uses Sun\u2019s floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or machining variations. It features a maximum operating capacity of 30 gpm (120 L/min) and demonstrates a typical response time of approximately 2 milliseconds. The valve's design allows for interchangeability among all three-port sequence cartridges of the same frame size, providing flexibility in system configurations. Other specifications include a check cracking pressure of 25 psi (1.7 bar), adjustment capabilities with five full clockwise turns to increase settings, and a maximum valve leakage at reseat of 10 drops per minute (0.7 cc/min). The SCEACAV model weighs approximately .60 lb (.30 kg) and includes Viton seals as part of its standard configuration.
