The pneumatic tri-eccentric hard seal butterfly valve is based on the two-eccentric hard seal butterfly valve to generate an angle(the sealing surface is an inclined cone) ， thus forming the tri-eccentric hard seal butterfly valve.The structure has no mechanical wear and scratch in the process of opening and closing， small closing torque， good cutting performance and long service life， as well as has two functions of adjustment and cutting. This series of products are widely used in the automatic control system of petroleum， chemical industry， electric power， metallurgy， environmental protection， light textile， papermaking and other industrial sectors. In addition， it's suitable for liquid， gas， coal gas， natural gas and steam to cut of for regulate flowcontrol.
