Imported electric adjustment and the structure characteristics of pneumatic valve

. Under high temperature and high pressure conditions, still has the stable sealing performance. Its special sealing system can be guaranteed from ultra-low temperature to ultra high temperature all the temperature range has high sealing performance
. Three-dimensional eccentric sealing system combined with the optimization design, make the pneumatic valves open small resistance. Butterfly plate sealing surface for the upward convex cone, open when the disc circumference of each point on the surface of the finish from sealing ring at the same time, the solid content is not easy to accumulate on the surface of the seal. Pneumatic valve closing is accomplished by elastic compression ring,
. The butterfly plate and sealing ring does not exist between the card phenomenon.
. Pneumatic valve sealing performance is not affected by temperature changes.
. Pneumatic valve stem diameter of axle seal using graphite compacting sealing ring. Above all ensures zero leakage and metal sealing and in front of the fire,, after all is zero leakage, therefore, is the nature of fire safety.
