119 ilot operated unloading relief valve () U UE - with shock damping valve ilot operated unloading relief valve () Overview he pilot operated unloading relief valve is used with either an accumulator or a two pump high-low circuit. One state being high flow low pressure and the other low flow high pressure. In the case of the accumulator circuit, when the pump discharge pressure reaches the cut-out pressure, the valve opens and the pump is unloaded. When the pressure on the accumulator side reaches the cut-in pressure, the valve is closed and the pump is loaded, pumping out the discharged oil to the accumulator side. In the case of the high-low circuit that uses two pumps, when pressure reaches the set pressure (cut-out pressure), the valve opens, pressure oil from the pumps is automatically returned to the tank and the pump is unloaded. When the pressure falls below the set pressure, the valve is closed and the pumps become automatically loaded.

124 ilot operated unloading relief valve (2) Overview he pilot operated unloading relief valve is used with either an accumulator or a two pump high-low circuit. One state being high flow low pressure and the other low flow high pressure. In the case of the accumulator circuit, when the pump discharge pressure reaches the cut-out pressure, the valve opens and the pump is unloaded. When the pressure on the accumulator side reaches the cut-in pressure, the valve is closed and the pump is loaded, pumping out the discharged oil to the ype indication accumulator side. In the case of the high-low circuit that uses two pumps, when pressure reaches the set pressure (cut-out pressure), the valve opens, pressure oil from the pumps is automatically returned to the tank and the pump is unloaded. When the pressure falls below the set pressure, the valve is closed and the pumps become automatically loaded. ilot operated unloading relief valve (2) ilot operated unloading relief valve Nominal dimension 35 Connection method F = = Gasket connection type Flange connection type Series number: 0 Shape of pressure adjusting part = Handle adjustment 2 = hread adjustment (with cap) 3 = Handle with key adjustment ype of hydraulic oil No symbol = Mineral based hydraulic oil V = hosphate ester based hydraulic oil W = Fatty ester based hydraulic oil Water-glycol based hydraulic oil Check valve provided or not No symbol = Without check valve ressure adjustment range 80 = 2.0 to 7.9Ma (20 to 80kgf/cm 2 ) 60 = 7.9 to 5.7Ma (80 to 60kgf/cm 2 ) 35 = 5.7 to.9ma (60 to 35kgf/cm 2 ) 2-37

226 Logic valve Logic valve KLD/LU port pressure port pressure External pilot pressure cover Cover Spring Sleeve Valve body Structure and operation of logic elements Without cushion overlap With cushion overlap Structure Logic elements consists of, as shown in the figure, a sleeve with internal seat, valve body, spring that always holds the valve body, and control ports, and the cover on which various types of valves and stroke limitters are to be installed. here are two types of valve body, with and without cushion overlap, each of which can be used for different usage. hough the valve body with the cushion overlap has higher flow resistance, it is used as a flow rate control valve in combination with a stroke limitter, or in order to tame switching shock under high pressure. Operation he hydraulic oil can flow in both direction of and, and open and close of the valve body are determined by the pressure in the pilot room. Hence, the pilot pressure is led internally or externally and controlled. Supposing that there is no pressure applied in the pilot room, the valve openes when the hydraulic force of or port becomes higher than the spring force, and if pressure is applied, the valve opens when the pressure of or port increases by the corresponding area ratio. he three areas shown in the figure significantly affect the functions. ssuming that the area is %, the ring shape area 2 is, depending on the type, 7% or 50%. Hence the area ratio :2 is 4.3:, or 2: respectively, and the area 3 which is computed by ( + 2) becomes 07% or 50% of respectively. he area 3 is determined by each nominal dimension and common to the types, while varies depending on the type.

311 Other general purpose valves SUN cartridge valve Features of SUN cartridge valve SUN cartridge valves adopt two piece structure called floating style. he body which has valve mounting threads and the sleeve which contains internal operating part are coupled with certain freedom, and the sleeve is, keeping slight gap in the axis direction between the locating shoulder and bottom shoulder, mounted in the cartridge hole (See the folowing figure). Hence, the tightening distortion due to cartridge mounting does not affect the internal operation part, which realises the stable operation. It smoothly operates at high pressure such as maximum working pressure 34.3Ma, and leakage amount is very slight. ecause four serieses each of which has different maximum flow rate are prepared for most of the cartridges, the best suited valve for your system will be found. () his part guides the cartridge hole to maintain the concentricity of cartridge valve and cartridge hole. (2) Having a slight gap between the cartridge hole and tip of the cartridge valve, the body which has cartridge valve mounting threads and the sleeve which contains internal operating part are coupled with certain freedom. (Floating style) (3) he floating style structure enables to tighten at high torque. s the result, the reliability has significantly increased against loosening or oil leakage. (4) his face called locating shoulder supports the axial force due to tightening, to prevent distortion on the sleeve portion. (5) Locating the thread portion at immediate proximity of the sleeve keeps the eccentricity of sleeve to minimum. (6) his face called bottom shoulder receives all the load that occurs during operation. (he load is not shared to the wire ring.) (7) Cartridge valves with various functions can be applied to the same cartridge hole, which provides flexibility in designing.
