The Sun Hydraulics SCEBCDV (SCEBCDV) is an atmospherically referenced, direct-acting sequence valve with an integrated reverse-flow check valve. This component is designed to supply a secondary circuit with flow once the pressure at the inlet port 1 surpasses the valve's set threshold. The incorporated check valve facilitates reverse flow from port 2 to port 1, ensuring efficient operation in load holding applications. The pressure setting of this sequence valve governs the pressure at port 1 relative to atmospheric venting, making it suitable for scenarios where a drain connection is not feasible. Constructed with Sun's floating style design, this valve minimizes the risk of internal part binding due to excessive installation torque or variations in cavity/cartridge machining. It boasts a capacity of 30 gpm (120 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The typical response time for this model is approximately 2 milliseconds, and it has a maximum leakage rate of 10 drops per minute (0.7 cc/min) upon reseat. The check cracking pressure is set at 25 psi (1.7 bar), and adjustments can be made using an internal hex screw with five clockwise turns required to increase the setting. The SCEBCDV model has a hex size of 1-1/8 inches (28.6 mm) and requires an installation torque between 45 to 50 lbf ft (61 to 68 Nm). Additionally, its locknut requires a torque setting between 80 to 90 lbf in (9 to 10 Nm). Weighing in at .60 lb (.30 kg), this sequence valve also comes with an optional Viton seal kit for enhanced durability and performance under various conditions.
