check valve. (Refer to valves without integral check when reverse free flow is not required.) "UR" Series Unloading Relief Valves with Integral Check Module An integral check valve prevents return flow from the accumulator through the unloading valve. In an accumulator system, the valve cuts out automatically when the accumulator pressure

performance pressure-unloading valves with an 3/4-16. UNF mounting thread. a pressure-relief function e.g. for protecting the pump (see.

They act deviating all the pump flow to the tank when the pressure value adjusted by the screw is reached, until the pressure in the working line B drops to a 

Unloading valves are pressure-control devices that are used to dump excess fluid to tank at little or no pressure. A common application is in hi-lo pump circuits where two pumps move an actuator at high speed and low pressure, the circuit then shifts to a single pump providing high pressure to perform work.

Regulating unloader valves can protect pumps and system components from surge shock damage that can occur when spray guns are shut off at high pressure. A pressure relief valve can bypass the required amount of water to help maintain constant system pressure and can help prevent damage to positive displacement pumps.

UNLOADING RELIEF VALVE (HRU) This type of valve consists of a balancing piston type unloading valve and a check valve assembled in one housing and is mainly used in accumulator circuits and circuits in which two levels of pressure (low-pressure large-volume circuit and high-pressure small-volume circuit) are handled.

Unloading Relief Valves Unloading Relief Valves These valves are used to operate the pumps with minimum load in accumulator circuits or in high-low pump circuits. In accumulator circuits, when the system pressure reaches to a cut out pressure (adjusted maximum), the valve acts to divert the pump

A relief valve which can be used in high-low pressure, unloading circuit. Specification. Model number, Maximum Pressure (kg/cm²), Connecting (PT), Maximum Flow.

The symbol for an unloading valve is similar to the symbol for a relief valve except that the pilot line is not connected to sense pressure 

Unloading relief valve BUCG series is used to circuit with oil storage, or pump in high-low pressure, to make sure the pump operation under the minimum
