費(fèi)斯托無論是在歐美還是在亞非，工業(yè)發(fā)達(dá)國家還是發(fā)展中國家，F(xiàn)ESTO供應(yīng)的都是同一高質(zhì)量標(biāo)準(zhǔn)的產(chǎn)品和服務(wù)，
減壓閥的壓力為P1的壓縮空氣，由左端輸入經(jīng)閥口10節(jié)流后，壓力降為P2輸出。P2的大小可由調(diào)壓彈簧2、3進(jìn)行調(diào)節(jié)。順時針旋轉(zhuǎn)旋鈕1，壓縮彈簧2、3及膜片5使閥芯8下移，增大閥口10的開度使P2增大。若反時針旋轉(zhuǎn)旋鈕1，閥口10的開度減小，P2隨之減小。
若P1瞬時升高，P2將隨之升高，使膜片氣室6內(nèi)壓力升高，在膜片5上產(chǎn)生的推力相應(yīng)增大，此推力破壞了原來力的平衡，使膜片5向上移動，有少部分氣流經(jīng)溢流孔12、排氣孔11排出。在膜片上移的同時，因復(fù)位彈簧9的作用，使閥芯8也向上移動，關(guān)小進(jìn)氣閥口10，節(jié)流作用加大，使輸出壓力下降，直至達(dá)到新的平衡為止，輸出壓力基本又回到原來值。若輸入壓力瞬時下降，輸出壓力也下降、膜片5下移，閥芯8隨之下移，進(jìn)氣閥口10開大，節(jié)流作用減小，使輸出壓力也基本回到原來值。逆時針旋轉(zhuǎn)旋鈕1。使調(diào)節(jié)彈簧2、3放松，氣體作用在膜片5上的推力大于調(diào)壓彈簧的作用力，膜片向上曲，靠復(fù)位彈簧的作用關(guān)閉進(jìn)氣閥口10。再旋轉(zhuǎn)旋鈕1，進(jìn)氣閥芯8的頂端與溢流閥座4將脫開，膜片氣室6中的壓縮空氣便經(jīng)溢流孔12、排氣孔11排出，使閥處于無輸出狀態(tài)。
