Angle Ball Valve

Ball valve can fast truncation, through to medium flow control unit in a pipeline system , to standardize the installation, use and maintenance, bronze ball valves are internal and external thread, card sets, flange, hot melt connection forms, are widely used in the system, such as water, gas, hvac, oil seal test strictly implement GB/T13927-1992 standard for general valve pressure test and pressure test before delivery 100% qualified, and shut gas factory, convenient detection seal performance before use.

Ball valve handle (handwheel) is designed according to the valve using environment and the corresponding torque, do not use the torque arm instead, so as to avoid the operation torque is too large and damage the valve, at the same time, too large closing speed will produce instant pressure multiplier water hammer effect.Frequent fluctuation of pipeline pressure or temperature will reduce its service life, and corresponding preventive measures should be designed.
