The Sun Hydraulics XQGELANCF (XQGELANCF) is a valve assembly designed for efficient accumulator charging using a fixed displacement pump. This system becomes operational when the pressure reaches the valve's set point, subsequently unloading the pump. Once the pressure decreases to a predetermined level, dictated by the pilot valve's fixed percentage, the pump re-engages to recharge the accumulator. The ventable relief within this assembly serves dual functions: it acts as a main stage for unloading the pump and provides overpressure relief for the system. For optimal performance, it is crucial to incorporate a separate drain line to avoid erratic operations due to tank line pressure fluctuations. When selecting an adjustment range, careful consideration is necessary as system pressure drops and flows can impact unloading valve operations. Low operating pressures combined with minimal differentials result in a narrow band between unload and reset, thus requiring precise system design. High flow rates typically lead to significant pressure drops, reducing the available differential for effective operation. The pressure setting and resultant reseat pressure are based on port 1 of the QPA pilot valve; therefore, expect higher pump pressures and lower accumulator pressures due to flow-induced pressure drops. This assembly features large porting relative to its capacity, encouraging large piping usage to minimize flow-induced pressure drop issues. The spool design of the pilot valve ensures maintenance of a fixed differential ratio through diameters that remain unchanged with use. It is essential that the accumulator pilot valve be set below any reliefs on the pump side of the system to prevent severe heating. Additionally, this package's relief is intended as an overpressure device and should be set higher than any pilot valve settings before being capped off. With a capacity of 40 gpm (160 L/min), this line-mounted body type offers robust performance in relevant applications.

This valve assembly is meant to charge an accumulator using a fixed displacement pump. When the pressure reaches the set point of the valve, the pump is unloaded. When the pressure drops to the value determined by the fixed percentage of the pilot valve, the pump is brought back on line to recharge the accumulator. The ventable relief serves a dual purpose as a main stage to unload the pump and as a system over-pressure relief.
- When applying this assembly, a separate drain line is required to prevent erratic operation caused by tank line pressure fluctuations.
- NOTE: Careful consideration should be given when selecting an adjustment range. System pressure drops and flows tend to affect the operation of unloading valves. Low operating pressures combined with low differentials result in a very narrow band between unload and reset, requiring precise system design. High flow rates typically mean high pressure drops, which subtract from the differential the valve has to work with.
- The pressure setting and the resultant reseat pressure are in reference to the port 1 area of the QPA* pilot valve. Pump pressure will be higher and accumulator pressure will be lower due to pressure drop caused by flow.
- The porting on this assembly is large in relation to its capacity. This is done to encourage the use of correspondingly large piping to minimize problems caused by flow induced pressure drop.
- The spool design of the pilot valve allows it to maintain a fixed differential ratio because the areas are created by diameters on the spool that will not wear or change with use.
- The accumulator pilot valve must be set below any reliefs in the pump side of the system or severe heating could occur.
- The relief in this package is meant to be an over-pressure device. It is set higher than the highest setting of the pilot valve and capped.

Notes:
- Important: Carefully consider the maximum system pressure. The pressure rating of the manifold is dependent on the manifold material, with the port type/size a secondary consideration. Manifolds constructed of aluminum are not rated for pressures higher than 3000 psi (210 bar), regardless of the port type/size specified.
