The Sun Hydraulics SQBBKNN (Material Number: SQBBKNN) is a kickdown sequence valve designed to provide an unrestricted flow path from port 1 to port 2 once the inlet pressure exceeds the valve setting. It remains open as long as the pressure at port 1 is greater than at port 2, and resets only when specific conditions are met. This valve is not suitable for load holding applications. It should be used on the actuator side of a system since flow must cease for resetting; if used on the pump side, pump flow must be stopped for reset. The valve features Sun's floating style construction to reduce binding risks due to installation torque or machining variations. The valve operates with a maximum pressure of 5000 psi (350 bar) and has a capacity of 7.5 gpm (30 L/min). It incorporates interchangeable three-port sequence cartridges and has a typical response time of 25 ms. The valve\u2019s leakage rate is minimal, with a maximum leakage of 2 in\u00b3/min (30 cc/min) at 110 SUS (24 cSt). The adjustment mechanism allows for increased settings through clockwise turns, and specific torque specifications are provided for installation and adjustments. Additionally, it uses Viton seals with a seal kit available under part number 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.
