進口自力式壓差調(diào)節(jié)閥
進口自力式壓差調(diào)節(jié)閥產(chǎn)品概述
美國WORK自力式壓差調(diào)節(jié)閥是一種無需外來能源的節(jié)能型控制閥，用于非腐蝕性液體和氣體溫度≤200℃的閥后（閥前）壓差控制裝置
自力式壓差調(diào)節(jié)閥（閥后）：當壓差升高時，閥門關(guān)閉
自力式壓差調(diào)節(jié)閥（閥前）：當壓差升高時，閥門開啟
產(chǎn)品特點
1：維護量小，介質(zhì)直接控制，無需外來能源控制的節(jié)能型控制閥
2：不銹鋼波紋管壓力平衡式，不平衡力小，靈敏度高
3：支持內(nèi)取壓和外取壓
4：設(shè)定點范圍寬，可通過調(diào)節(jié)螺母方便的調(diào)整設(shè)定點
5：執(zhí)行器與彈簧可隨意組培，從而實現(xiàn)多種調(diào)節(jié)范圍
6：對于高密封要求，使用軟密封閥芯
7：采用標準模塊化設(shè)計，三化水平高，通過組合件，可進行多項組合控制
