The Sun Hydraulics SQFBOWN (SQFBOWN) is a high-performance kickdown sequence valve designed to manage hydraulic flow efficiently. This valve is engineered to kick completely open and maintain an open state once the inlet pressure at port 1 surpasses the preset threshold, facilitating an unrestricted flow from port 1 to port 2. The valve remains open as long as the inlet pressure exceeds the outlet pressure. It resets only when the pressure at port 1 drops below its setting, flow ceases between ports, and the pressure at port 2 is equal to or greater than that at port 1. Notably, all three-port sequence cartridges are interchangeable within the same frame size and cavity, ensuring versatility in various applications. This model is not recommended for load-holding tasks but excels in actuator-side operations where flow cessation allows for resetting. It features a robust construction with a main stage orifice shielded by a 150-micron stainless steel screen and can handle pressures up to 5000 psi (350 bar). The response time is typically around 25 milliseconds with minimal leakage of up to 3 in\u00b3/min (50 cc/min) at specified conditions. The SQFBOWN model incorporates Sun's floating style construction, minimizing potential binding issues due to installation torque or machining variations. With a capacity of handling flows up to 30 gpm (120 L/min), this valve offers reliable performance for precise hydraulic control applications. Installation requires specific torque settings, and adjustments can be made using its internal hex screw. The product weighs approximately .50 lb (.25 kg) and comes with Viton seal kits for optimal durability under various operating conditions.
