6 Inch Butterfly Valve
Description of 6 Inch Butterfly Valve:
As a valve company, ZECO provides detailed installation instructions to ensure high performance and long service life of the 6 wafer butterfly valve. The capacity if piping flanges and valve depends the deformation of gaskets. Acting force of bolting is not only resists force to loosen the connection, but also to keep necessary compressing stress. Taking note of the force does not exceed the gasket load and pressure load. In order to ensure good connection, following instructions shall be noted.
(a) Check flange surface, if any defect appears leakage, groove or impress, repair before installation;
(b) The installation requests of Cast iron flange are more than the ductile cast iron. Proposed to use low-strength steel Bolted to reduce as a result of excessive pre-compression flange of the possibility of exceeding the prescribed stress. To fit flat flange gasket in the flat flange to prevent excessive torque of bolt flange damage. Should not be confused with convex planar flange of the loaded flange In the cast iron flange connection is particularly important that the top is installed on the better to ensure that in the absence of excessive load bolted gasket circumstances make an appropriate compaction force;
(c) Gasket have the capacity of resisting deformation and damage;
(d) Check the centration of assemble-part flanges, Lubricate the threads of boltings. Boltings shall be fasten sequential to make sure level contact between flange and gasket.
