Because of the nickel cock pneumatic valve

pure nickel cock pneumatic valve is with hole plug body as the opening and closing, the plug body with the pneumatic valve rod rotation, in order to realize the opening and closing action of pneumatic valve. Plug body as the cone, and a cylinder, cock the pneumatic valves open and close quickly, simple structure, small fluid resistance. Products are widely used in petroleum, chemical industry, water and electricity, food, medicine, textile, paper making, refining and other industrial piping has a simple structure, opening and closing fast, easy operation, convenient maintenance, good sealing, etc.
pure nickel cock pneumatic valve is the main corrosion characteristics in all the caustic solution concentration and temperature are very resistant to corrosion and crack and alkali resistant performance. Mainly used as the working condition of high temperature and strong alkali corrosion medium.

for secco nickel cock pneumatic valve product features:
. 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 full open position, generate enough sealing pressure, seal achieve zero leakage.
。 Double groove seal ring, can make the soft sealing bushing, solid migration in pneumatic valve body does not produce, also can absorb trace deformation caused by temperature change bushing, between liner and cock at the same time produce strong squeezing effect, in order to improve the service life of the sealing surface.
。 Upper shaft adopts a unique PTFE ( Or reinforced PTFE) Diaphragm and wedge and adjusting gasket combination, can adjust the sealing surface sealing pressure ratio, flexible to rotate the plug, and can ensure the seal on import and export and flange connection.
。 PTFE sealing bushing, it can be used according to the temperature and working medium with different filler, good lubrication and long life.
。 Metal lip at the inlet and outlet of the pneumatic valve body lumen in cock turns, such as scraping effect, pneumatic valve no cavity for medium accumulation at the same time, especially suitable for viscous, easy fouling and crystallization conditions.
