Description

Electric Motor Natural Gas Fully Welded Ball Valve Pipeline Valves

Product Description

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.

Double Block and Bleed (DBB) Function

DBB Function

When valve in fully open or closed position,the upstream and downstream seat blocks the fluid,so the sediment

in the cavity can be drained out,this structure have below function:

1. In-line inspection seat leakage

2. In working pressure, valve in full open or close position.Available to replace stem packing on line.

Open drain valve to bleed medium in cavity,it can reduce medium pressure on stem sealing ring,which

to extend the seal service life.
