The Sun Hydraulics SQHBLCN (Material Number: SQHBLCN) is a sophisticated kickdown sequence valve designed to manage flow in hydraulic systems by opening completely and maintaining an open state once the inlet port 1 pressure surpasses the valve setting. This creates an unrestricted flow path from port 1 to port 2. The valve remains open as long as the pressure at port 1 is higher than at port 2, and resets only when the pressure at port 1 drops below the set level. It is important to note that this valve should not be used in load-holding applications. The main stage orifice is protected by a robust 150-micron stainless steel screen, ensuring durability and performance. The pressure at drain port 3 can directly add to the valve setting in a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). The SQHBLCN is intended for use on the actuator side of hydraulic systems, requiring flow cessation through the valve for resetting. If applied on the pump side, pump flow must be halted for resetting. It features Sun's floating style construction to prevent internal binding due to installation torque or machining variations. This model has a capacity of up to 60 gpm (240 L/min) and operates efficiently with a typical response time of just 25 milliseconds. With factory pressure settings established at kickdown points and a maximum operating pressure of 5000 psi (350 bar), this valve provides reliable performance in demanding applications. The SQHBLCN has minimal leakage rates and offers adjustable settings with precise control over its operation through clockwise turns on its adjustment screw, ensuring flexibility for various system requirements.
