The Sun Hydraulics SQFBKAV (SQFBKAV) is a specialized kickdown sequence valve designed to open completely and maintain an unrestricted flow path from port 1 to port 2 once the inlet pressure exceeds the valve's setting. This mechanism ensures efficient fluid management, particularly when used on the actuator side of a hydraulic system. The valve remains open as long as the pressure at port 1 is greater than at port 2, and it resets only when these conditions are reversed. It features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in high-pressure environments up to 5000 psi (350 bar). The valve incorporates Sun\u2019s floating style construction, which minimizes internal binding due to installation torque or machining variations. With a capacity of 30 gpm (120 L/min) and a typical response time of 25 ms, it is suitable for applications requiring quick actuation. Note that this valve should not be used in load-holding applications due to its specific operational characteristics. Installation requires careful adherence to specified torque values, with an installation torque between 45-50 lbf ft (61-68 Nm). The adjustment screw features an internal hex size of 5/32 inches (4 mm), allowing precise control over the pressure settings with up to five clockwise turns available for adjustment. The SQFBKAV model offers robust performance with minimal leakage, making it ideal for high-demand hydraulic systems where reliable sequencing is critical.
