Top entry ball valve has a special construction that allows easy in-line maintenance by quick accessing to its internal parts for inspection and repairing. When any failure of the valve in pipeline occurs, the entire valve does not need to be disassembled from the pipeline, the bonnet and stem can be easily removed by removing flange screws and nuts, enabling the ball and the seats to be freely accessible and taken out.
Nominal size: NPS 1/2"-NPS 60" (DN15-DN1500)
Pressure: CL150-CL2500 (PN10-PN420)
Temperature range: -196°C to +550°C
Valve operation: manual, bevel gear, pneumatic, electric, pneumatic-hydraulic, electro-hydraulic, etc.
Blowout-proof stem design is adopted to ensure the precise position of the ball;
Double block & bleed (DBB), coupled with fire safe design and antistatic device;
Easy in-line maintenance, eliminating the need for disassembling of the entire ball valve, greatly reducing the maintenance time;
During the maintenance process, the fluid media from pipeline can be retained appropriately to minimize the energy loss; This also reduce workload prior to the maintenance, significantly facilitating the maintenance operation;
