美國posi-flate 氣動執(zhí)行器 蝶閥專家
Posi-flate 蝶閥*的設計， 采用氣體壓力使閥座向著閥盤伸展， 以便于隨時為密封提供均勻分布的壓力。 由于在閥門的開啟和關閉期間， 閥盤和閥座只會發(fā)生瞬時接觸， 從而使閥盤僅受到輕微的碰撞。 相反，對于一般的蝶閥來說，閥盤擦過閥座產生的碰撞，會降低閥門的性能和壽命。
實際上，打開和關閉Posi-flate蝶閥時只需要很小的扭矩。 這樣可以使用較小的執(zhí)行器，從而降低整個閥門的成本。
實際上，根據(jù)實際比較測試和現(xiàn)場應用記錄，Posi-flate蝶閥性能*于所有的閥門。 事實上， 一個Posi-flate蝶閥的壽命能達到一至三百萬次循環(huán)周期， 甚至在嚴重磨損的情況下也能使用，這是不同尋常的。 對于干燥的固體、氣體和泥漿體，使用Posi-flate 膨脹式蝶閥。
膨脹式蝶閥585/586系列是為zui苛刻的條件而設計的。閥座是為重載和更高的操作壓力而設計的。閥門的尺寸范圍為2〞(50mm) - 24〞(600mm) , 適用于ANSI和公制法蘭標準。 系列齊全的執(zhí)行器，限位開關和控制裝置能有效地滿足不同的應用要求。

The Tork-Mate 890 series extended life actuators are ideal for the operation of 90° turn devices such as butterfly valves, ball valves, plug valves, damper valves and other devices. Tork-Mate pneumatic actuators have features that are unique, providing many benefits to the user looking for worry-free service.
TMHC 2324
A proprietary two-step hardcoat process that offers superior protecion on interior and exterior housing surfaces. TMHC 2324 also ensures maximum life from the piston seals, piston bearings and heel bearings.
NAMUR Mounting
Tork-Mate 890 series actuators meet the latest NAMUR standards, allowing direct or close coupling of NAMUR designed accessories. The pinion interface features a positive, international standard drive for positioners, switches and other accessories. The solenoid interface allows direct acceptance of any NAMUR designed control valves.
Modular
Easily removable end caps and modular spring packs simplify the conversion from double-acting to spring-return configurations.
Travel Adjustment
The Tork-Mate 890 series actuators feature pinion travel stops that allow a full +/-10° of valve travel adjustment. As an option, extended stroke adjustment screws can be added for inexpensive throttling applications.
Extended Cycle Life
Special piston seals provide greatly extended life compared to standard O-ring actuators. All other bearings, seals and components have been engineered to provide superior and extended service lives.
Blow-out Proof Pinion Gear
In addition to the stainless steel pinion retaining ring, the Tork-Mate 890 series actuators feature a unique internal safety bar.
Operating Ranges
Tork-Mate 890 series double-acting actuators produce guaranteed minimum torque outputs up to 17,466 inch pounds (1973 Nm).
Custom Options
These include Viton® seals, high temperature trim up to 250° F (121° C), special finishes, stainless steel pinions, special mounting configurations and special coupling configurations.
