The Sun Hydraulics SQHBKCV (SQHBKCV) is a highly specialized kickdown sequence valve designed to provide an unrestricted flow path once the pressure at inlet port 1 exceeds the valve setting. This valve remains open as long as the pressure at port 1 surpasses that of port 2, ensuring efficient flow management. It is crucial for applications where flow must cease to reset, making it ideal for use on the actuator side of a hydraulic system. The valve's main stage orifice is safeguarded by a 150-micron stainless steel screen, and it boasts a maximum operating pressure of 5000 psi (350 bar). The factory pressure settings are established at the kickdown point, with a typical response time of 25 ms. Physically and functionally interchangeable with all three-port sequence cartridges, this model should not be used in load-holding applications. It features Sun Hydraulics' floating style construction, minimizing internal part binding risks due to excessive installation torque or machining variations. The SQHBKCV has a capacity of 60 gpm (240 L/min) and exhibits minimal leakage with a maximum valve leakage rate of 4 in\u00b3/min (65 cc/min) at 110 SUS (24 cSt). Adjustments can be made by turning the adjustment screw clockwise up to five turns to increase settings. Installation requires specific torque specifications: the valve hex size is 1\u00bc inches (31.8 mm), with an installation torque range between 150-160 lbf\u00b7ft (203-217 Nm). The adjustment screw internal hex size is ^5/32 inches (4 mm), and the locknut hex size is ^9/16 inches (15 mm), requiring a locknut torque of 80-90 lbf\u00b7in (9-10 Nm). Weighing in at approximately 1.50 lb (0.70 kg), this valve is built for durability and precision in demanding hydraulic environments.

Kick-down sequence valves will kick completely open and remain open once the pressure at the inlet (port 1) exceeds the valve setting, creating an unrestricted flow path from port 1 to port 2 (sequence). The pressure setting at port 1 is relative to the drain (port 3). The valve remains open as long as the pressure at port 1 exceeds the pressure at port 2. To reset the valve, pressure at port 1 must fall below the setting of the valve, flow from port 1 to port 2 must cease, and pressure at port 2 must be equal to or greater than the pressure at port 1.
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- Should not be used in load holding applications.
- The main stage orifice is protected by a 150 micron stainless steel screen.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Intended for use on the actuator side of the system as flow through the valve must cease for the valve to reset. If used on the pump side of a system, pump flow must be shut off for the valve to reset.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
