Forged Steel Fully Welded Ball Valve BS 6755 For Natural Gas Pipeline

Product Description

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.

Design standard:	API6D, ASME B16.34, BS5351, ISO17292,DIN
Face to Face:	ASME B16.10, API 6D
Actuator:	electrical actuator,pnenmatic actuator,penumatic-hydraulic actuator etc.
Nominal diameter:	2” – 48” (DN 15-DN 1200)
Pressure :	CLASS 150 – CLASS 2500 (PN10- PN120)
Butt Welding:	ANSI B16.25,ASME B 31.8,ASME B31.4
Gasket:	ASME B 16.20
Bolt and Nut	A193-B7, A194-2H / A193-B7M, A194-8M

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.
