玫森乃兰公司几年前研制的ΣF调节阀,既保持常规调节阀的特点,又有所创新。它采用侧装的膜头,并与曲柄连杆传动结合,使执行机构的输出力比常规调节阀大数倍。使常规调节阀一向在高压差,大口径方面难于解决的问题获得较好的解决;使调节阀具有更广泛的用途。由于其结构的改进,使ΣF调节阀更便于使用,维护和保养。如果配上4600型阀门定位器,它可以使调节阀的品种规格大大简化,有利于调节阀的标准化,通用化,系列化。
Rosemount Nairan company developed a few years ago ΣF control valve, both to maintain the characteristics of conventional control valve, but also innovative. It uses a side mounted film head, and with the crank connecting rod drive, so that the output of the implementing agencies than the conventional control valve several times. So that conventional control valve has always been in high pressure, large diameter difficult to solve the problem get a better solution; make the valve has a wider range of uses. Due to its structural improvements, ΣF regulating valve is easier to use, maintain and maintain. If coupled with 4600-type valve positioner, which can greatly simplify the specifications of the control valve is conducive to the standardization of regulating valve, universal, series.
