The Sun Hydraulics SQDBJQV (SQDBJQV) is a precision-engineered kickdown sequence valve designed to provide an efficient and reliable solution for managing hydraulic flow in various systems. This valve is specifically crafted to kick completely open and maintain an unrestricted flow path from port 1 to port 2 once the inlet pressure surpasses the valve setting. It remains open as long as the pressure at port 1 exceeds that at port 2, ensuring smooth operation within its designated parameters. The valve automatically resets when the pressure at port 1 falls below the set threshold, ceasing flow from port 1 to port 2, with pressure at port 2 equal to or greater than at port 1. This model is part of a series of interchangeable three-port sequence cartridges, allowing for versatile application across different systems. It features a robust construction that includes a main stage orifice protected by a 150-micron stainless steel screen. The valve is not recommended for load holding applications due to its specific operational design. With a maximum operating pressure of 5000 psi (350 bar), it\u2019s crucial that the pressure at port 3 does not exceed this limit as it's directly additive to the valve setting. The SQDBJQV is particularly suited for use on the actuator side of hydraulic systems, requiring flow cessation for resetting purposes. Its corrosion-resistant design options make it ideal for deployment in harsh environments, with external components available in stainless steel or zinc-nickel plating configurations. Additional features include Sun's floating style construction, which minimizes internal binding risks due to installation torque variations. The valve has a factory-set kickdown point, with adjustment capabilities allowing up to five clockwise turns to increase settings. The unit's compact design ensures ease of installation and maintenance within hydraulic systems requiring precise sequencing capabilities.

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.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
- 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.
