The Sun Hydraulics SQHBLAN (SQHBLAN) is a kickdown sequence valve designed to provide a reliable solution for managing hydraulic flow in various systems. This valve is engineered to kick completely open and maintain an unrestricted flow path from port 1 to port 2 once the pressure at the inlet port 1 surpasses the preset valve setting. It remains open as long as the pressure at port 1 exceeds that at port 2, requiring pressure from port 1 to fall below the set threshold and equalize with or exceed pressure at port 2 for reset. The SQHBLAN model features a robust construction with a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and longevity in demanding environments. This sequence valve is not recommended for load-holding applications and should be used on the actuator side of systems, as flow cessation through the valve is necessary for resetting. It incorporates Sun's floating style construction, reducing risks of internal part binding due to installation torque or machining variations. The SQHBLAN supports pressures up to 5000 psi (350 bar) and offers a maximum capacity of 60 gpm (240 L/min). Its design allows it to be physically and functionally interchangeable with other three-port sequence cartridges within its frame size. Additional specifications include a typical response time of 25 ms and minimal leakage rates under specific conditions. The valve's adjustment can be modified through clockwise turns, with precise torque requirements detailed for installation and maintenance procedures. For enhanced performance, it utilizes Viton seals available in an optional cartridge kit. With its comprehensive capabilities, the Sun Hydraulics SQHBLAN is well-suited for controlling hydraulic sequences efficiently in complex systems.

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.
