The Sun Hydraulics SQHBLWV (SQHBLWV) is a sophisticated kickdown sequence valve designed for hydraulic systems requiring precise pressure control. This valve activates when the inlet port 1 pressure surpasses the set threshold, allowing an unrestricted flow from port 1 to port 2. It remains open as long as the pressure at port 1 exceeds that at port 2, ensuring efficient system operation. The valve is reset by reducing the pressure below its setting and ceasing flow from port 1 to port 2. Notably, it features a robust design with a stainless steel screen protecting the main stage orifice and incorporates Sun's floating style construction to minimize internal binding risks. With a maximum operating pressure of 5000 psi (350 bar) and a capacity of 60 gpm (240 L/min), this valve is suitable for high-pressure applications but is not recommended for load-holding scenarios. The valve's installation and adjustment specifications include a hex size of 1-1/4 in (31.8 mm) and an installation torque range of 150-160 lbf ft (203-217 Nm). Its compact design, weighing only 1.50 lb (0.70 kg), makes it versatile for various setups, particularly on the actuator side where flow cessation is necessary for resetting. Additionally, it includes a Viton seal kit option for enhanced durability under demanding conditions, making it an ideal choice for reliable hydraulic sequencing tasks.

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.
