本公司(sī)生産的系列自(zi)力式微壓調節(jiē)閥是一種無需(xu)外🌈來能源的 節(jiē)能型産品，利用(yòng)工業管道中介(jie)質的壓力變👅化(huà)與信号進行比(bi)較， 使被調節介(jiè)質的力與執行(háng)機構的輸出力(li)平衡，以達到穩(wěn)定壓力、 差壓值(zhí)。 

The series of self operated micro pressure regulating valve produced by the company is an energy-saving product without external energy. The pressure change and signal of the medium in the process pipe- line are compared to make the force of the regulated medium and the output force of the actuator balance， so as to achieve stable pressure and differential pressure.
