Ball Valve Flanged 2-way Ball Valve


Completely insulated with the medium


low torque , high pressure resistance, pressure beared with two sides, the fluid totally insulated with the valve body and shaft; no plug between the valve ball with the valve shaft, convenient to maintain and replace, and imbedded with special anti-stuck self-lubricating bearing inside the shaft so as to end the problem that the normal ball valve is not able to be closed.


International compatibility


An flange is mounted on the top of the valve which conform to the ISO5211 standard. The manual operation mechanism or automatic actuators can be installed with it directly. All of the valve can be mounted with Extended valve neck according to the working conditions to meet the requirement for low temperature or high temperature.


Mounting platform for upright type


because of standardization design, all of the actuators including handle, gear, pneumatic and electric ones can be connected with this series flange ball valves without additional support. Easy to be mounted on site and reducing the error and height.


Diversified customization
