上海良工閥門廠截止閥系列 名稱：截止閥 型號：J41H(T/W)/J44H(T/W)/J11H(T/W)/J43HF/J641H/J941H 材質：WCB/CF3/304/316L/灰鑄鐵等 工作溫度：-29~500ºC 簡介：截止閥，也叫截門，是使用最廣泛的一種閥門，它之所以廣受歡迎，是由于開閉過程中密封面之間摩擦力小，比較耐用，開啟高度不大，制造容易，維修方便，不僅適用于中 低壓，而且適用于高壓。截止閥的閉合原理是，依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質流通。截止閥只許介質單向流動，安裝時有方向性。截止閥—上海良工閥門系列產品：高壓截止閥。高溫截止閥。高壓高溫截止閥。電動截止閥J941H/J961Y。氣動截止閥J641H。氣動角座閥。日標截止閥J41W。德標截止閥。美標截止閥J41W。保溫截止閥BJ41H/BJ45。高溫截止閥J41Y/J61Y。高壓截止閥J41H、對焊截止閥J61Y/J65Y/J64H。高溫高壓截止閥。Y形截止閥J45/J65Y。自密封截止閥J41W/J61W。黃銅截止閥J11W。鑄鐵截止閥J41TW。鑄鋼截止閥J41H。鍛鋼截止閥。不銹鋼截止閥J41W。鉻鉬鋼截止閥J41Y-100I。波紋管截止閥WJ41/WJ44/WJ61H、保溫波紋管截止閥BWJ41W。絲口截止閥J11W。法蘭截止閥J41。氧氣截止閥JY41W。真空截止閥NKJ41H/44H/J61。水封截止閥DS41H/DS61H。傘齒輪截止閥J541H。氨用截止閥J41B/J42B/J61B/J21B/J11B。角式截止閥J44H。襯氟截止閥J41F4/J45F4。襯膠截上閥J41J/J45J。塑料截止閥J41F-6S、J11F-6S。液化氣截止閥J41F。天燃氣截止閥J41N。低溫截止閥DJ41W。撞擊式大口徑截止閥。蒸汽截止閥。斯派沙克式截止閥。節流閥、高壓節流閥、截止節流平衡閥L41Y/L44Y/L46Y/L86Y/L87Y/L66Y/L67Y/L47Y。節流截止放空閥FJ41Y。節流截止排污閥TPJ41Y。 閥體的材質有: 鑄鐵、鑄鋼、不銹鋼、鍛鋼、鉻鉬鋼、鉻鉬釩鋼。
