進口自力式壓差調節閥
進口自力式壓差調節閥產品概述
美國WORK自力式壓差調節閥是一種無需外來能源的節能型控制閥，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
自力式壓差調節閥（閥后）：當壓差升高時，閥門關閉
自力式壓差調節閥（閥前）：當壓差升高時，閥門開啟
產品特點
1：維護量小，介質直接控制，無需外來能源控制的節能型控制閥
2：不銹鋼波紋管壓力平衡式，不平衡力小，靈敏度高
3：支持內取壓和外取壓
4：設定點范圍寬，可通過調節螺母方便的調整設定點
5：執行器與彈簧可隨意組培，從而實現多種調節范圍
6：對于高密封要求，使用軟密封閥芯
7：采用標準模塊化設計，三化水平高，通過組合件，可進行多項組合控制
