QFZ COMBINATION VALVES FOR ACCUMULATOR CONTROL

 The combination valve for accumulator control is made up of high-pressure ball stop valve, direct-control overflow valve and a small stop valve. The high-pressure ball stop valve serves as a manual-operated main switch valve, the direct-control overflow valve as a safety valve and the small stop valve as a load relief valve. It is a valve combination indispensable to the circuit of accumulator in a hydraulic system. Another characteristic of QFZ combination valve for accumulator control is that connection is achieved through direct welding of flange, which may significantly lower the installation position of accumulators.
