The Sun Hydraulics SQBBKCV (SQBBKCV) is a kickdown sequence valve designed to create an unrestricted flow path from port 1 to port 2 once the pressure at the inlet port exceeds the preset valve setting. This valve is particularly useful in applications where maintaining an open state is essential after the initial pressure threshold is surpassed. The valve remains open as long as the pressure at port 1 stays above that at port 2, and it requires specific conditions to reset: pressure at port 1 must drop below its setting, flow from port 1 to port 2 must stop, and pressure at port 2 must be equal to or greater than that at port 1. Notably, this valve should not be used in load-holding applications due to its design characteristics. The SQBBKCV features a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 7.5 gpm (30 L/min). The response time for this model is typically around 25 ms, with minimal leakage rates of about 30 cc/min under specified conditions. Its construction incorporates Sun's floating style design, which minimizes potential internal part binding caused by excessive installation torque or machining variations. The valve's adjustment settings allow for fine-tuning through clockwise turns, with specific hex sizes provided for both the adjustment screw and locknut. This model is intended for use on the actuator side of hydraulic systems due to its requirement for flow cessation for resetting purposes. It can be installed interchangeably with other three-port sequence cartridges within its series, offering flexibility in system design configurations. The SQBBKCV includes Viton seals and comes with detailed specifications regarding installation torque and adjustment parameters, ensuring reliable performance in various hydraulic applications.

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.
- Should not be used in load holding applications.
- 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.
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- 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.
