The Sun Hydraulics SQHBLWN (Material Number: SQHBLWN) is a kickdown sequence valve designed for hydraulic systems requiring an open flow path once a specific pressure threshold is exceeded. This valve activates when the pressure at inlet port 1 surpasses the set valve pressure, allowing unrestricted flow from port 1 to port 2. The valve remains open as long as this pressure condition is met, and it resets only when the pressure at port 1 drops below the valve setting and flow ceases. Notably, this model should not be used in load-holding applications due to its design characteristics. Physically and functionally interchangeable with other 3-port sequence cartridges of similar frame size, this valve features a main stage orifice protected by a 150-micron stainless steel screen. The maximum operating pressure is capped at 5000 psi (350 bar), with response times typically around 25 ms. The installation involves specific torque settings for both the valve and locknut to ensure proper functionality without internal binding. Designed for use on the actuator side of hydraulic systems, it incorporates Sun's floating style construction to minimize potential issues arising from installation variations. With a capacity of 60 gpm (240 L/min), this model offers reliable performance in appropriate applications. Additional specifications include a factory-set kickdown point, maximum leakage of approximately 4 in\u00b3/min at standard viscosity, and compatibility with Viton seal kits.

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.
