POSI-flate*蝶阀设计采用空气压力，扩大座位针对光盘，为一泡沫密封每次均匀的压力分布，。由于座椅使得与阀的开闭过程中的光盘仅偶然接触，有zui小的光盘冲击。这是相对于传统蝶阀其中光盘冲击导致的座椅的剃须，降低整体性能和阀的使用寿命。
基本上较小的转矩要求来打开和关闭Posi-flate蝶阀，从而较小的致动器可以使用导致较低的整体阀成本。
在实际的对比测试和记录现场的应用，POSI-flate蝶阀的表现优于其他所有的阀门。事实上，一到三百万次，甚至在严重磨损的一个POSI-flate蝶阀的生活，并不少见。对于干燥的固体，气体和泥浆的应用，POSI-flate膨胀式蝶阀是的。
该POSI-flate系列五百八十六分之五百八十五膨胀式蝶阀是专为zui苛刻的条件。座椅被设计用于重型应用和更高的操作压力。标准阀门的尺寸范围从2“（50mm）的24”（600毫米），并符合ANSI和公制法兰标准。执行器提供全系列，限位开关和控制，可满足个人申请。
Posi-flate's unique butterfly valve design uses air pressure to expand the seat against the disc, providing even pressure distribution for a bubble-tight seal, every time. Because the seat makes only casual contact with the disc during valve opening and closing, there is minimal disc impingement. This is in contrast to conventional butterfly valves where disc impingement leads to shaving of the seat, decreasing the overall performance and valve life.
Substantially less torque is required to open and close the Posi-flate butterfly valve, thus a smaller actuator can be used resulting in lower overall valve cost.
In actual comparison tests and documented field applications, the Posi-flate butterfly valve outperformed all other valves. In fact, a Posi-flate valve life of one to three million cycles, even in extremely abrasive applications, is not uncommon. For dry solids, gases and slurry applications, the Posi-flate inflatable seated butterfly valve is unsurpassed.
The Posi-flate Series 585/586 inflatable seated butterfly valves are designed for the most severe conditions. The seat is designed for heavy duty applications and higher operating pressures. Standard valve sizes range from 2" (50mm) to 24" (600mm) and fit both ANSI and metric flanges. A full line of actuators, limit switches and controls are available to suit individual applications.
