Posi-flate*的蝶閥設(shè)計(jì)采用氣壓擴(kuò)大閥座對閥瓣,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)際的對比測試和記錄現(xiàn)場應(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.
