Welded ball valve _ Full bore welded ball valve

Comprehensive information compilation of full bore welded ball valves, combined with mainstream market products and technical parameters:

1、 Product Overview
The Full bore welded ball valve adopts a fully welded structure, and the valve body is directly welded to the pipeline without any risk of leakage. It is suitable for long-distance pipelines such as natural gas, petroleum, and heating. Its core features include:
Zero leakage sealing: using carbon reinforced PTFE inclined elastic sealing ring to achieve complete sealing.
Maintenance free design: no exposed moving parts, long-term reliable operation.
Full bore structure: no reduction design, low pressure loss, high flow rate.
2、 Technical parameters
Parameter specification range remarks
Some manufacturers support customized larger diameters for nominal diameters ranging from DN15 to DN1500 (2 "to 60")
Pressure rating PN1.6~PN40 (ANSI 150~2500lb) High pressure models require special design
Suitable for temperatures ranging from -29 ℃ to+350 ℃. High temperature models can reach up to 600 ℃
Drive mode manual/turbo/electric/pneumatic electric model supports remote control
