美国posi-flate 气动执行器 蝶阀专家
Posi-flate 蝶阀*的设计， 采用气体压力使阀座向着阀盘伸展， 以便于随时为密封提供均匀分布的压力。 由于在阀门的开启和关闭期间， 阀盘和阀座只会发生瞬时接触， 从而使阀盘仅受到轻微的碰撞。 相反，对于一般的蝶阀来说，阀盘擦过阀座产生的碰撞，会降低阀门的性能和寿命。
实际上，打开和关闭Posi-flate蝶阀时只需要很小的扭矩。 这样可以使用较小的执行器，从而降低整个阀门的成本。
实际上，根据实际比较测试和现场应用记录，Posi-flate蝶阀性能*于所有的阀门。 事实上， 一个Posi-flate蝶阀的寿命能达到一至三百万次循环周期， 甚至在严重磨损的情况下也能使用，这是不同寻常的。 对于干燥的固体、气体和泥浆体，使用Posi-flate 膨胀式蝶阀。
膨胀式蝶阀585/586系列是为zui苛刻的条件而设计的。阀座是为重载和更高的操作压力而设计的。阀门的尺寸范围为2〞(50mm) - 24〞(600mm) , 适用于ANSI和公制法兰标准。 系列齐全的执行器，限位开关和控制装置能有效地满足不同的应用要求。

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.
