Asphalt special pneumatic valve is introduced

asphalt dedicated pneumatic valve ( Aka cock pneumatic valve) Belong to the pneumatic valve, the opening and closing it. ( Cone plug or ball revolve around its centerline cock pneumatic valve is with hole plug body as open-close part, through the rotation of the plug body and pneumatic valve stem implement action of pneumatic valve opening and closing. Asphalt is special pneumatic valve has simple structure, opening and closing rapidly, fluid resistance small, in recent years, as the history of one of the first people to adopt pneumatic valves were not only no longer be pneumatic ball valve and other types of pneumatic valve is replaced, but the trend of the market is more and more popular.
asphalt special pneumatic valve advantages:
. Pneumatic valve import and export side window design for double groove seal ring structure, plug in the process of rotation, the seal between the sealing pressure ratio in the gradual change, until she reached full open or close position, generate enough sealing pressure, seal achieve zero leakage.
. Double dao grooved ring that can make the PTFE liner firmly in the pneumatic valve body does not produce displacement, and can absorb trace deformation caused by temperature change bushing, at the same time between liner and cock powerful cleaning effect, and improve the service life of the sealing surface.
. The whole process of sealing can approximate that has nothing to do with the pressure in the pipeline.
. PTFE liner inside, according to the materials used in different temperature and medium filling, good lubrication and long life.
