進口先導(dǎo)式減壓閥—德國沃德（WODE）集導(dǎo)閥和主閥于一體，導(dǎo)閥的設(shè)計與直接作用式減壓閥類似,是一種高性能、外部取壓、大流量的減壓閥，無論上游壓力的變化或下游負(fù)荷的波動，德國沃德（WODE）減壓閥均能實現(xiàn)穩(wěn)定的壓力控制。Pilot type valve set the pilot valve and the main valve, similar to the design of the pilot valve direct acting pressure reducing valve is a high performance, external to take pressure, large traffic pressure reducing valve, regardless of upstream pressure changes ordownstream load fluctuations, pressure reducing valve can achieve stable pressure control進口先導(dǎo)式減壓閥導(dǎo)閥主要由閥座、閥瓣、膜片、彈簧、調(diào)節(jié)彈簧等零件組成。通過調(diào)節(jié)調(diào)節(jié)彈簧壓力設(shè)定出口壓力、利用膜片傳感出口壓力變化，通過導(dǎo)閥啟閉驅(qū)動活塞調(diào)節(jié)主閥節(jié)流部位過流面積的大小，實現(xiàn)減壓穩(wěn)壓功能，該產(chǎn)品主要用于蒸汽管路，起減壓穩(wěn)壓作用。
