Posi-flate*的蝶阀设计采用气压扩大阀座对阀瓣,甚至提供气密密封的压力分布,每一次。因为座位让只有偶然接触阀瓣阀开启和关闭期间,有zui小的圆盘撞击。这与传统蝶阀阀瓣撞击导致剃须的阀座,减少总体性能和阀门life.的生活。
大大减少扭矩需要打开和关闭Posi-flate蝶阀,因此可以使用更小的执行机构阀门降低总体成本。
在实际的对比测试和记录现场应用,Posi-flate蝶阀outperformed all other valves. 比其他所有阀门。In fact, a Posi-flate事实上,Posi-flatevalve life of one to three million cycles,阀门的使用寿命的三百万周期,even in extremely abrasive applications, is not即使在极其磨料应用,不是uncommon. 少见。For dry solids, gases and slurry干燥的固体,气体和泥浆applications, the Posi-flate inflatable seated应用程序,Posi-flate充气就座butterfly valve is unsurpassed.蝶阀是的。
The Posi-flate 蝶阀是专为zuisevere conditions. 严重的条件。The seat is designed座椅设计for heavy duty applications and higher对于重型应用程序和更高operating pressures. 操作压力。Standard valve sizes标准阀尺寸range from 2" (50mm) to 24" (600mm) and fit范围从2”(50毫米)24”(600毫米)和健康both ANSI and metric flanges. ANSI和公制法兰。A full line of完整的线actuators, limit switches and controls are致动器、限位开关和控制available to suit individual applications.根据单独的应用程序可用。
