Dan fuss electric flanged globe valve products overview:

The globe valve opening and closing is plug valve, sealing surfaces appear flat or cone, disc make linear movement along the centerline of fluid. Stem form of exercise, there is lifting lever (valve rod, the handwheel don't lift), there are also lift rotating lever (hand wheel rotating lifting with the valve stem and nut in the body). Globe valve used throughout close tu, don't allow to adjust and throttling.

The main characteristics and USES electric flanged globe valve

1. Compact structure, reasonable design, the valve rigidity, smooth channel, small flow resistance coefficient.

2. The sealing surface of stainless steel and carbide, long service life

3. Using the flexible graphite packing, reliable seal, flexible operation of the light

4. Drive way to break up, electric, pneumatic, gear, structure: elastic wedge single ram, rigid wedge single ram and double disc type.

5. Widely used in petrochemical, oil, steam pipeline, such as coal-fired power plants connected or truncate the medium inside the pipe opening and closing device.
