The Sun Hydraulics SQBBCCN (SQBBCCN) is a kickdown sequence valve designed for hydraulic systems where controlling the flow path is crucial. This valve automatically kicks open and remains open once the pressure at the inlet port 1 surpasses its set threshold, allowing unrestricted flow from port 1 to port 2. The valve stays open as long as the pressure at port 1 exceeds that at port 2, and it resets only when pressure conditions reverse. Notably, it should not be used in load-holding applications due to its design characteristics. The valve's setting is directly influenced by the pressure at drain port 3, which should not exceed 5000 psi (350 bar). It is optimized for use on the actuator side of hydraulic systems, requiring cessation of flow for resetting; if used on the pump side, pump flow must be halted for reset. The SQBBCCN incorporates Sun's floating style construction to minimize internal part binding from installation torque or machining variations. It features a cavity T-163A with a capacity of 7.5 gpm (30 L/min), and operates effectively up to a maximum pressure of 5000 psi (350 bar). With a typical response time of 25 ms and minimal leakage, this sequence valve offers reliable performance in demanding environments. Adjustments can be made with up to five clockwise turns to increase settings, utilizing an internal hex size of 5/32 inches for precision adjustments. Its compact size, with a model weight of just .30 lb (.15 kg), makes it suitable for various configurations without adding significant weight to systems.
