本公司生産的(de)系列自力式微壓(yā)調節閥是一種無(wú)⛷️需外來🈲能源的 節(jiē)能型産品，利用工(gōng)業管道中介質的(de)壓力變化與信号(hao)進行比較， 使被調(diao)節介質的力與執(zhi)行機構的輸出力(li)📞平衡，以達到穩定(dìng)壓力、 差壓值。 

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.
