意大利 ITALVALVOLE Shut-off valves 截止閥 開關(guān)閥
12288/B – IVS DN025 H070 CF8M BW EPDM 2WNC MS-O
截止閥,也稱為開關(guān)閥,是用于攔截工業(yè)過(guò)程流體的設(shè)備。它們由各種材料制成,取決于壓力、溫度條件以及與輸送的流體的相容性。用于閥體的最常用材料是灰鑄鐵和球墨鑄鐵(GJL 250和GJS 500)、碳鋼(WCB)和不銹鋼(CF8M)。
這些閥門經(jīng)過(guò)設(shè)計(jì),以優(yōu)化最大流量和 Kv,并盡量減小載荷損失。截止閥采用2或3個(gè)口,具有方形閥體、角座和流體傳遞。它們安裝在標(biāo)準(zhǔn)工藝行業(yè),例如染色工業(yè)、紡織工業(yè)、化工業(yè)、熱調(diào)節(jié)過(guò)程以及食品和制藥應(yīng)用中。
該系列包括氣動(dòng)操作版本,通過(guò)氣動(dòng)執(zhí)行器,帶有簡(jiǎn)單彈簧返回或雙氣動(dòng)效果,允許閘板打開和關(guān)閉,從而攔截流程流體。還有手動(dòng)操作的系列,通過(guò)旋轉(zhuǎn)手輪調(diào)節(jié)閥門的開啟。
