Ball Valve
API6D cylindrical fixed flange ball valve
The pressure loss of a ball valve under nominal flow rate is the smallest among all valve types, equivalent to the flow resistance coefficient of a pipe with the same length, almost zero; Our company's reduced-bore ball valve, through fluid analysis and theoretical calculation, has a flow path design that maximizes the valve's flow capacity and reduces the flow resistance generated by the reduced-bore section.
API6D cylindrical fixed full-welded underground ball valve
The pressure loss of a ball valve under nominal flow rate is the smallest among all valve types, equivalent to the flow resistance coefficient of a pipe with the same length, almost zero; our company's reduced-bore ball valve has undergone fluid analysis and theoretical calculation, and the flow path design maximizes the valve's flow capacity and reduces the flow resistance generated by the reduced-bore section.

API6D Cylindrical Fully Welded Fixed Ball Valve
The pressure loss of ball valves at nominal flow is the smallest among all valve types, equivalent to the flow resistance coefficient of a pipeline of the same length, almost zero; Our company's reduced bore ball valves, through fluid analysis and theoretical calculations, have a flow channel design that maximizes the valve's flow capacity and reduces the flow resistance generated by the reduced bore section.

DN600 oval fixed welded ball valve
Fixed ball structure: the fixed structure of the ball with upper and lower rotary axis, the lower part of the ball inlaid bearings, fixed by the lower stem, the upper part of the stem and the upper stem is connected, the ball can only be rotated along the axis of the valve channel vertical movement, not like floating ball valves as the ball can be moved to the side, so the fixed ball valves work, the pressure of the fluid in front of the valve and the spring force to push the valve seat tightly pressed to the ball, to form a reliable prevalent valve sealing! Fixed ball valves have DBB function, that is, the valve can simultaneously cut off the pipeline upstream and downstream of the media, the valve sealing is safe and reliable.
