The Sun Hydraulics SQJBCWV (SQJBCWV) is a kickdown sequence valve designed to create an unrestricted flow path from port 1 to port 2 once the inlet pressure exceeds the valve's setting. This valve remains open as long as the pressure at port 1 surpasses that at port 2, and it resets only when the pressure at port 1 drops below its setting, with flow ceasing and equal or greater pressure at port 2 compared to port 1. Ideal for actuator-side applications, this valve should not be used in load-holding scenarios. It features a main stage orifice protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction to prevent internal parts binding due to installation torque or machining variations. The valve can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of up to 120 gpm (480 L/min). Its response time is typically around 25 ms, with maximum valve leakage of about 5 in\u00b3/min (80 cc/min) at viscosity levels of 110 SUS (24 cSt). The adjustment mechanism allows for up to five clockwise turns to increase the setting. The installation torque ranges from 350 to 375 lbf ft (474 to 508 Nm), while the locknut requires a torque of 80 to 90 lbf in (9 to 10 Nm). The model weighs approximately 3.10 lb (1.40 kg), and it uses a Viton seal kit identified as part number: 990019006.
