The Sun Hydraulics SXEALAN (SXEALAN) is a direct-acting sequence valve designed to manage hydraulic flow in secondary circuits once the pressure at inlet port 1 surpasses the valve's set threshold. This valve is capable of controlling the pressure at port 1 in relation to the drain port 3, making it ideal for load-holding applications. The SXEALAN features a zero pilot flow design, necessitating that port 3 be connected to maintain a proper pressure reference within the control chamber. Blocking port 3 can lead to valve malfunction due to reciprocating seal weepage. The valve allows for pressures up to 5000 psi (350 bar) at port 3, which are directly proportional to the valve setting at a 1:1 ratio. This model incorporates Sun's floating style construction, reducing the risk of internal part binding caused by excessive installation torque or machining variations in cavity/cartridge settings. It fits into T-2A cavities and provides a capacity of up to 30 gpm (120 L/min). Factory pressure settings are established at a flow rate of 2 in\u00b3/min (30 cc/min), with a maximum operating pressure of 5000 psi (350 bar). Its typical response time is approximately 2 milliseconds, and it maintains minimal leakage with a maximum valve leakage rate of 10 drops/minute (0.7 cc/min) upon reseat. For adjustments, there are four clockwise turns available to increase the setting, with specific hex sizes for different components: valve hex size is 1-1/8 inches (28.6 mm), adjustment screw internal hex size is 5/32 inches (4 mm), and locknut hex size is 9/16 inches (15 mm). Installation torque ranges from 45-50 lbf-ft (61-68 Nm), while locknut torque ranges from 80-90 lbf-in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits under cartridge number: 990202006.
