The Sun Hydraulics SQHBKCN (SQHBKCN) is a kickdown sequence valve designed to kick completely open and remain open once the pressure at the inlet port 1 exceeds the valve setting. This creates an unrestricted flow path from port 1 to port 2, with the pressure setting at port 1 being relative to the drain port 3. The valve remains open as long as the pressure at port 1 exceeds that at port 2. To reset, pressure at port 1 must fall below the valve setting, flow from port 1 to 2 must cease, and pressure at port 2 must be equal to or greater than that at port 1. This model is physically and functionally interchangeable with other three-port sequence cartridges of the same frame size but should not be used in load-holding applications. It features a main stage orifice protected by a 150-micron stainless steel screen, and pressure at port 3 should not exceed 5000 psi (350 bar). The SQHBKCN is intended for use on the actuator side of systems, requiring cessation of flow through the valve for resetting. It incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. With a capacity of up to 60 gpm (240 L/min) and factory pressure settings established at kickdown points, this valve operates under a maximum pressure of 5000 psi (350 bar) with a typical response time of about 25 ms. The maximum leakage rate is specified as four cubic inches per minute (65 cc/min) at standard viscosity conditions. Adjustments can be made via an internal hex screw, with specific torque values provided for installation and locknut adjustments. The model weighs approximately 1.50 lb (0.70 kg), and it utilizes Viton seals for enhanced durability in hydraulic applications.

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.
