The Sun Hydraulics SQHBCAN (Material Number: SQHBCAN) is a high-performance kickdown sequence valve designed to optimize fluid flow in hydraulic systems. This valve is engineered to kick completely open and maintain an open state once the pressure at the inlet port 1 surpasses the preset valve setting, enabling an unrestricted flow from port 1 to port 2. The valve is specifically crafted for applications where it is crucial that the pressure at port 1 remains above that at port 2 for continued operation. It features a floating style construction, which minimizes the risk of internal component binding due to excessive installation torque or machining variations. The SQHBCAN model incorporates a stainless steel screen to protect its main stage orifice and can handle pressures up to 5000 psi (350 bar). It offers a capacity of up to 60 gpm (240 L/min) and has a typical response time of 25 milliseconds. The valve's performance ensures minimal leakage with specifications indicating a maximum leakage of 4 in\u00b3/min (65 cc/min) at 110 SUS (24 cSt). This sequence valve is interchangeable with other three-port sequence cartridges within its frame size, offering flexibility in various system configurations. However, it is not recommended for load-holding applications as it requires cessation of flow from port 1 to port 2 and equalization of pressure between ports for resetting. Installation requires specific torque settings, with the valve hex size being 1\u00bc inches (31.8 mm), and installation torque ranging from 150-160 lbf-ft (203-217 Nm). The adjustment screw features an internal hex size of ^5/32 inches (4 mm), while the locknut hex size is ^9/16 inches (15 mm), requiring a torque setting between 80-90 lbf-in (9-10 Nm). This robust component weighs approximately 1.50 lb (0.70 kg) and comes with a Viton seal kit option for enhanced durability in demanding environments.

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.
