Product Details

NSV supplies Flanged Fully Welded Ball Valves, trunnion mounted, for onshore and offshore topside applications in the Oil & Gas transmission. Fully welded ball valve offers the advantage of a compact envelope, which allows for increased strength and significant reduction in weight. Furthermore, since the body is made by welding forged parts, there are fewer potential leak paths when compared to side-entry.

STRUCTURAL FEATURES

1. Integral Valve Structure
It is welded by forged steel. The forging materials are subjected to ultrasonic examination according to ASME nondestructive flaw detection requirements. The welding slope on the connection face is subjected to liquid penetration examination.

2. Corrosion Resistance And Sulfide Stress Resistance
Certain corrosion allowance is left for the body wall thickness. The carbon steel stem, fixed shaft, ball, seat and seat ring are subjected to chemical nickel plating according to ASTM B733 and B656. In addition, various corrosion resistance materials are available for users to select.
According to customer requirements, the valve materials can be selected according to NACE MR 0175/ISO 15156 or NACE MR 0103, and strict quality control and quality inspection should be carried out during the manufacturing so as to fully meet the requirements in the standards and meet the service conditions in sulfurization environment.

3. Double Block And Bleed(DBB)
When the valve is closed and the middle cavity is emptied through the discharge valve, the upstream and downstream seats will independently block the fluid at the inlet and outlet to realize double block function. Another function of the discharge device is that the valve seat can be checked if there is any leakage during the test. In addition, the deposits inside the body can be washed and discharged through the discharge device to reduce damage to the seat by impurities in the medium.
