The Sun Hydraulics SQBBCNN (SQBBCNN) is a kickdown sequence valve designed to facilitate an unrestricted flow path from port 1 to port 2 once the pressure at port 1 exceeds the valve's set threshold. This mechanism is particularly useful in applications where maintaining continuous flow is critical, as the valve remains open as long as the inlet pressure surpasses outlet pressure. The valve is designed for use on the actuator side of hydraulic systems, requiring cessation of flow for reset, making it unsuitable for load-holding applications. It features a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of 7.5 gpm (30 L/min). The valve incorporates Sun's floating style construction, which helps prevent internal binding due to torque or machining variations. With a response time typically around 25 ms and minimal leakage at standard conditions, this sequence valve ensures efficient operation in demanding environments. The adjustable settings allow for precise control with up to five clockwise turns needed to increase the setting, and it includes specific torque requirements for installation and adjustment components. Additionally, this model offers interchangeability with other three-port sequence cartridges within its frame size, enhancing flexibility in system design and maintenance.
