The Sun Hydraulics RQEBCBV (Material Number: RQEBCBV) is a kickdown relief cartridge designed to function similarly to a circuit breaker in hydraulic systems. This valve is engineered to kick open completely and maintain an open state once the inlet port 1 pressure surpasses the set threshold, allowing unrestricted flow from port 1 to tank port 2. It remains open as long as the pressure at port 1 exceeds that at port 2, and resets only when flow ceases and equal or greater pressure is established at port 2. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability and reliability in operation. Notably, this valve is unsuitable for load-holding applications and should be used on the actuator side of hydraulic systems since flow must stop for resetting. Back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. This valve incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. The RQEBCBV model features a cavity T-10A Series 1 with a capacity of up to 25 gpm (95 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar). It boasts a typical response time of approximately 25 milliseconds and minimal leakage rates under specific conditions. The adjustment mechanism allows for setting increases with five clockwise turns, while installation requires specific torque settings for optimal performance. Weighing only .30 lb (.15 kg), this cartridge valve offers robust performance in corrosive environments when configured with appropriate external components like stainless steel or zinc-nickel plating. A Viton seal kit is available for maintenance needs, enhancing its application versatility in various hydraulic scenarios such as portable grain augers where safety mechanisms are critical.

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.
