The PARKER RU101S30C unloading relief valve in the United States automatically controls the flow of the hydraulic pump to charge one or more accumulators, providing design flexibility. The Parker RU101 series is a small flow pilot valve that can be used to control the flow of larger quantitative or load sensing hydraulic pumps.
The Parker RU101S30C is an externally pilot controlled unloading valve with a rated flow rate of 1 gpm and a working pressure of up to 3000 psi. It is typically used in conjunction with a quantitative pump to directly unload a flow rate of no more than 1 gpm, or to pilot a logic element to unload larger hydraulic pump flows. Once the accumulator is filled to the regulated or factory pre-set maximum pressure, the hydraulic pump flow will be automatically unloaded back to the tank.
The Parker unloading relief valve RU101 series provided by Shanghai Danaco adopts hydraulic control to unload the accumulator when the pump is charged, so there is no need for components such as solenoid valves, pressure sensors, electrical controllers, and auxiliary connecting wires. The Parker RU101S30C can be applied in various hydraulic industries, such as construction, mining equipment, industrial hydraulic power units, oil and gas equipment, marine equipment, material handling equipment, etc.
