Installation and Commissioning of Wafer Triple Offset Butterfly Valve

When installing, close the valve first and then install it to prevent damage to the sealing surface of the disc. The two flanges should be parallel so that the contact force between the valve and the flanges is uniform after installation. The inner hole of the pipeline flange shall not be too large, and shall be no more than 5mm, in case the pressure position of the pressure plate is wrong and deformation failure occurs. For specific use, please consult ZECO Valve Group.
