The Sun Hydraulics SCEBCEV (SCEBCEV) is an atmospherically referenced, direct-acting sequence valve equipped with a reverse-flow check. It is designed to supply a secondary circuit with flow once the pressure at the inlet port 1 surpasses the valve setting. This valve features an integral check valve that facilitates reverse flow from port 2 to port 1. The pressure setting of this sequence valve manages the pressure at port 1 in relation to the atmospheric vent, making it suitable for load holding applications. It is important to note that atmospherically referenced valves are ideal in situations where a drain connection is not feasible, although they may leak externally or allow moisture ingress over time. The Sun floating style construction of this valve minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. The SCEBCEV operates within a maximum capacity of 30 gpm (120 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at 2 in/min (30 cc/min), and it exhibits a typical response time of 2 ms. The maximum valve leakage at reseat is limited to 10 drops/min (0.7 cc/min), and it incorporates a check cracking pressure of 25 psi (1.7 bar). Adjustment involves up to five clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. This model has a weight of .60 lb (0.30 kg) and uses Viton seal kits for cartridge sealing, ensuring reliability in hydraulic systems where precise control and sequencing are essential.
