Forged Steel Fully Welded Ball Valve Used In City Gas Pipeline
Product Description
Fully Welded Ball Valve is trunnion mounted, and the high-strength forged stem is housed in a PTFE-impregnated
stainless steel bearing for smooth operation. The trunnion-mounted stem absorbs thrust from line pressure and
prevents excessive friction between the ball and seat, so operating torque remains low even at full rated operating pressure.

Advantage
Fully Welded Ball Valve provide maximum strength with minimum weight and maximum resistance to pipeline
pressure and stress. The compact spherical design also eliminates body flanges, reducing overall size and
leakage paths. Fully welded ball valves (welded body ball valves) are ideal for buried applications to reduce
potential leak points and reduce potential flange fugitive emissions.
Fully welded ball valve with excellent performance and advantages can ensure the safe and reliable operation
of long-distance pipeline and city gas pipeline.
