The Sun Hydraulics SQJBCCV (SQJBCCV) is a kickdown sequence valve designed for hydraulic systems, providing an efficient means of managing flow once the pressure at the inlet port exceeds a predetermined setting. This valve facilitates an unrestricted flow path from port 1 to port 2 when activated, remaining open as long as the inlet pressure surpasses the outlet pressure. A distinctive feature of this valve is its ability to reset only when the inlet pressure drops below the set threshold and flow ceases, making it ideal for use on the actuator side of a system. It should not be employed in load-holding applications due to its design characteristics. The SQJBCCV is built with Sun's floating style construction, minimizing internal binding risks caused by installation torque or machining variations. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability under high-pressure conditions up to 5000 psi (350 bar). This valve offers a response time of approximately 25 milliseconds and supports a maximum capacity of 120 gpm (480 L/min). Additionally, it features adjustable settings with up to five clockwise turns for increased pressure regulation. Installation requires specific torque values for various components, including a locknut torque of 80-90 lbf-in (9-10 Nm). Weighing in at 3.10 lbs (1.40 kg), this model incorporates Viton seals for optimal performance in demanding 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.
