Insulation pneumatic butterfly valves brief introduction:

Of heat preservation for cold insulation BD643H pneumatic butterfly valve has good properties, and the valve and pipe diameter, one to medium flows in a straight line, small resistance, easy is most suitable for solidification, high viscosity liquid medium. At the same time, can effectively reduce the medium inside the pipeline heat loss. Taiwan minister insulation butterfly valve with pneumatic jacketed integral jacket design, more evenly heat preservation, cold. Jacket, the body of the lateral and jacketed control of welding allows the highest pressure steam or cold water for 1 mpa. Is mainly used in petroleum, chemical, pharmaceutical, food and other kinds of systems, in order to transport under normal temperature solidification of high viscosity medium.

Butterfly valve pneumatic heat preservation principle:

Insulation pneumatic butterfly valve, also known as jacketed butterfly valve, which is in common triple eccentric metal hard seal butterfly valves in the valve body on the basis of the external welding metal jacket, insulation in butterfly valve body jacket on both sides of interface, can contain an overheating steam or other gas, in order to prevent the medium or solidification crystallization at room temperature condition. Heat preservation butterfly valve flange than ordinary metal hard seal butterfly valve to freshman year to two specifications, mainly used in oil, chemical, metallurgical, pharmaceutical and other kinds of systems.

Insulation pneumatic butterfly valve technology parameters:

Insulation pneumatic butterfly valve shaft seal is made up of rotation between the butterfly plate and valve seat surface and rubber to control, use a rubber seal surface and rubber bag lined butterfly plate, ensure the valve spindle is not in contact with the cavity fluid, tight sealing performance, long service life and can be used for fast cut off or adjust flow, is suitable for reliable sealing and good regulation characteristics required.
