The Sun Hydraulics SQBBCWV (SQBBCWV) is a kickdown sequence valve designed to open completely and remain open once the pressure at the inlet port 1 surpasses the valve setting, facilitating an unrestricted flow from port 1 to port 2. The valve's operation is contingent on the pressure at port 1 being greater than that at port 2, and it will reset only when the pressure at port 1 falls below its set threshold, flow ceases, and pressure at port 2 equals or exceeds that of port 1. This valve is not suitable for load-holding applications. It should be noted that any pressure at drain port 3 adds directly to the valve setting in a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). The SQBBCWV is intended for use on the actuator side of systems as flow must stop for reset; if utilized on the pump side, pump flow must be halted for resetting. All three-port sequence cartridges are interchangeable in terms of flow path and cavity compatibility within a given frame size. The valve incorporates Sun's floating style construction to reduce internal binding risks due to excessive installation torque or machining variations. It features a capacity of 7.5 gpm (30 L/min) and operates with a maximum pressure of 5000 psi (350 bar). The typical response time is around 25 ms, with minimal leakage rates under specified conditions. Adjustments can be made by turning clockwise up to five full turns to increase settings, with specific torque requirements for installation and locknut adjustments provided. The product weighs approximately .30 lb (.15 kg) and utilizes Viton seals as part of its cartridge seal kit (990163006).

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.
