 Posi-flate*的蝶閥設(shè)計(jì)采用氣壓擴(kuò)大閥座對(duì)閥瓣,甚至提供氣密密封的壓力分布,每一次。因?yàn)樽蛔屩挥信既唤佑|閥瓣閥開啟和關(guān)閉期間,有zui小的圓盤撞擊。這與傳統(tǒng)蝶閥閥瓣撞擊導(dǎo)致剃須的閥座,減少總體性能和閥門life.的生活。
大大減少扭矩需要打開和關(guān)閉Posi-flate蝶閥,因此可以使用更小的執(zhí)行機(jī)構(gòu)閥門降低總體成本。
在實(shí)際的對(duì)比測(cè)試和記錄現(xiàn)場(chǎng)應(yīng)用,Posi-flate蝶閥outperformed all other valves. 比其他所有閥門。In fact, a Posi-flate事實(shí)上,Posi-flatevalve life of one to three million cycles,閥門的使用壽命的三百萬周期,even in extremely abrasive applications, is not即使在極其磨料應(yīng)用,不是uncommon. 少見。For dry solids, gases and slurry干燥的固體,氣體和泥漿applications, the Posi-flate inflatable seated應(yīng)用程序,Posi-flate充氣就座butterfly valve is unsurpassed.蝶閥是的。
The Posi-flate 蝶閥是專為zuisevere conditions. 嚴(yán)重的條件。The seat is designed座椅設(shè)計(jì)for heavy duty applications and higher對(duì)于重型應(yīng)用程序和更高operating pressures. 操作壓力。Standard valve sizes標(biāo)準(zhǔn)閥尺寸range from 2" (50mm) to 24" (600mm) and fit范圍從2”(50毫米)24”(600毫米)和健康both ANSI and metric flanges. ANSI和公制法蘭。A full line of完整的線actuators, limit switches and controls are致動(dòng)器、限位開關(guān)和控制available to suit individual applications.根據(jù)單獨(dú)的應(yīng)用程序可用。
