The valve opening area is computed as a function of the excess in the pressure drop, either a simple linear expression or a (generally nonlinear) tabulated function. The valve serves its purpose until its opening area reaches a maximum—a point at the limit of the valve regulation range, ...
The surface area, namely, the load area of the valve flap arranged on the valve seat mouth is large, and setting pressure can be regulated conveniently, so that the utility model has the advantages of high sensitivity, wide purpose, high stability of pressure-relief operation, safe use, etc...
PURPOSE:To make it possible to produce a back pressure to secure a working oil pressure even if a relief valve is in an open condition by selecting a shorter stroke length of a poppet of the relief valve arranged at a control valve for controlling the pressure oil in a power line. CONSTI...
PURPOSE:To prevent generation of impulsive sound accompanied with movement of vibrationproof member by insertedly fitting an annular member to the small diameter part of a valve body sliding in the valve hole of a relief valve, arranging a vibrationproof member between one side of the annular mem...
