The Sun Hydraulics SQHBLBV (SQHBLBV) is a high-performance kickdown sequence valve designed for hydraulic systems requiring precise pressure control and flow management. This valve is engineered to kick completely open and maintain an open state when the pressure at inlet port 1 surpasses the preset valve setting, allowing unrestricted flow from port 1 to port 2. The reset mechanism requires the pressure at port 1 to fall below the set threshold, cessation of flow from port 1 to port 2, and equal or greater pressure at port 2 compared to port 1. This model is part of a series where all three-port sequence cartridges are interchangeable in terms of flow path and cavity size. It features a main stage orifice protected by a durable 150-micron stainless steel screen and should not be utilized in load-holding applications. With a maximum operating pressure of up to 5000 psi (350 bar), this valve is intended for use on the actuator side of hydraulic systems, as it requires cessation of flow through the valve for resetting purposes. The SQHBLBV incorporates Sun's floating style construction, which minimizes potential binding issues due to installation torque or machining variations. It has a capacity of up to 60 gpm (240 L/min), with factory pressure settings established at the kickdown point. The response time is typically around 25 ms, ensuring quick adaptation to changing system pressures. Installation involves specific torque requirements: valve hex size is 1-1/4 inches (31.8 mm) with an installation torque range between 150-160 lbf ft (203-217 Nm). The adjustment screw uses an internal hex size of 5/32 inches (4 mm), while the locknut requires a torque range of 80-90 lbf in (9-10 Nm).

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.
