The corrosion resistant pneumatic ball valve is of eccentric metal sealing structure, and the sealing form is metal to metal sealing. The replaceable metal sealing ring is metal sealing, and the stainless steel plate and graphite composite plate sealing ring is metal sealing. In addition to electric drive, hard seal butterfly valves are also driven by manual, worm gear drive, pneumatic, etc. The butterfly plate of the corrosion resistant pneumatic ball valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the hard sealed pneumatic ball valve body, the disc shaped butterfly plate rotates around the axis with a rotation angle of 0~90. When it rotates to 90, the valve is fully open. 　　

Precautions before using stainless steel pneumatic butterfly valve 2
Precautions before using stainless steel pneumatic butterfly valve 2. If the device of stainless steel pneumatic butterfly valve is attached with operation instructions, please stop the device according to the instructions
When piping is connected, please do not bend excessively, and bend the local radius. Please pay attention to: a If there is a moving piping, use the piping that is not less than the reciprocating bending radius b for static use, and use the minimum bending radius as the criterion to perform the connection operation. 3. When piping is connected, please prevent the pipe body from presenting a twist state, because the pipe body cannot absorb the twist deformation. When connecting by flange, first fix one side of the flange. In addition, when it is necessary to further tighten the thread connection, please pay attention not to make the pipe body appear twisted deformation. 4. Stainless steel pneumatic butterfly valve should not make the pipe body be installed in a tight state. For the pipe body with external mesh sleeve, the woven mesh sleeve is an important pressure resistant part. The net sleeve cannot be fully tensioned after being installed in a tight state. When it is transported in a loose state, the pressure bearing strength of the pipe body will be extremely reduced. It is very risky. 5 Please confirm the seal. For products sealed with seals, please confirm whether the product body can be equipped with seals 6. For stainless steel pneumatic butterfly valves, please use special seals. Local product seals are provided by the manufacturer as standard subordinate products. As it is a special seal, please be sure to use this subordinate product. Seals other than those subject to the specification may leak. When the change operation is stopped, if the material changes, please contact our factory to communicate the precautions that broad users should know before using the pneumatic butterfly valve 1
