本公司(sī)生産的(de)系列自(zì)力式微(wēi)壓調節(jie)閥是一(yi)種無需(xu)外來能(néng)源的 節(jie)能型産(chǎn)品，利用(yong)工業管(guǎn)道中介(jie)質的壓(yā)🚶力變❤️化(huà)與信号(hào)進行比(bǐ)較， 使被(bei)調節介(jiè)質的力(lì)💛與執行(hang)機構的(de)輸出力(lì)平衡，以(yi)達到穩(wěn)定壓力(li)、 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.
