The Sun Hydraulics RQEBKCN (RQEBKCN) is a kickdown relief cartridge designed to function similarly to a circuit breaker within hydraulic systems. It activates by completely opening and maintaining an open state when the pressure at inlet port 1 surpasses the valve setting, allowing unrestricted flow from port 1 to tank port 2. The valve remains open as long as the pressure differential between ports 1 and 2 persists, and it resets only when flow ceases and pressure at port 2 equals or exceeds that at port 1. This cartridge is protected by a 150-micron stainless steel screen, ensuring durability and reliability in operation. It is not suitable for load-holding applications due to its reset requirements, which necessitate cessation of flow for valve resetting. Primarily intended for use on the actuator side of systems, using it on the pump side requires pump flow cessation for resetting. The RQEBKCN model features corrosion-resistant construction options identified by suffixes AP or LH, indicating external stainless steel or zinc-nickel plated components respectively. The valve incorporates Sun's floating style construction to minimize internal binding risks caused by excessive installation torque or machining variations in cavities/cartridges. With a capacity of up to 25 gpm (95 L/min) and a maximum operating pressure of 5000 psi (350 bar), this cartridge offers robust performance with minimal leakage at specified conditions. Its design includes specific adjustment features such as a clockwise turn mechanism for setting increase, along with defined hex sizes for both adjustment screw and locknut. The product is lightweight at .30 lb (.15 kg) and comes with a Viton seal kit (990010006). An example application includes portable grain augers where quick release under pressure is critical for safety.

Kick-down relief cartridges act similar to a circuit breaker in an electrical system. The valves will kick completely open and remain open once the pressure at the inlet (port 1) exceeds the valve settting, creating an unrestricted flow path from port 1 to tank (port 2). The valve remains open as long as the pressure at port 1 exceeds the pressure at port 2. To reset 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.
- To reset valve, flow through the cartridge must cease.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- Not suitable for use in load holding applications.
- 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.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
- 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.
