The Sun Hydraulics SXEALCN (SXEALCN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This valve regulates pressure at port 1 relative to the drain port 3, making it suitable for load-holding applications. It features a zero pilot flow design, requiring port 3 to be connected to maintain a pressure reference in the control chamber. Blocking port 3 can lead to malfunction due to reciprocating seal weepage. The valve's setting is directly influenced by the pressure at port 3 at a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). The SXEALCN incorporates Sun's floating style construction, reducing the risk of internal binding caused by excessive installation torque or variations in cavity/cartridge machining. It fits into cavity T-2A and offers a capacity of up to 30 gpm (120 L/min). Factory pressure settings are established at flows of 2 in\u00b3/min (30 cc/min), with a maximum operating pressure of 5000 psi (350 bar) and typical response time of around 2 milliseconds. The valve exhibits minimal leakage at reseat, limited to 10 drops per minute (0.7 cc/min). Adjustment requires approximately four clockwise turns to increase settings, with specific dimensions provided for installation and adjustment tools. The SXEALCN weighs approximately .60 lb (.30 kg) and utilizes Viton seals for optimal performance.
