Floating ball valve is for medium and low pressure conditions for various corrosive and non-corrosive mediums.Body of floating ball valve may be integral or combined type.Floating ball valve manufactured by BTL may be divided into cast steel floating ball valve and forged steel floating ball valve by different material forming approaches. There are soft sealing floating ball valve and metal sealing ball valve by sealing material.User may select full-size or reducing structure as required. The aperture of rate of full-size valve shall be same with inner diameter of pipeline for pipeline cleaning.
Structural Features:
1、Valve body selection of high quality materials ,long service life
2、ST floating ball valve using lip seal seat, sealing performance is good, low friction coefficient, small operating force
3、It has fire prevention and antistatic device
4、The stem has an anti-flight configuration
5、A handle indicating the state of the switch.The flat - headed stem is well connected to the handle to ensure that the on-off state indicated by the handle is consistent with the valve.
6、The floating ball valve is suitable for frequent operation with quick closing and opening;Small in size and light in weight;Not subject to the direction of installation;Low fluid resistance, no vibration, low noise.
