Spherical Fully Welded Ball Valve

The body is single welded connected by two hemispherical, the valve parts with compact spherical body perfectly in one set, in the same time it has maximum strength and minimum weight, and a maximum resistance ability to pipeline pressure and stress, compact spherical valve body design avoids body connected by flange, thus reducing valve shape dimension and eradicated leakage channels, avoid toxic and flammable fluids from leaking to the outside of ball valve and cause unnecessary environmental pollution and personal injury, to ensure the safe operation of the pipeline. Life can be a maximum of 20 years.

Technical Specification:

Nominal Diameter:DN50 (2”) ~ DN 1400 (56”)?

Pressure Range:ANSI Class 150 ~900, PN 16 ~ 160?

Working Temperature:-29?(-20?) ~ +425?(797?)?

Operation:Lever, gear, pneumatic, electric, hydraulic, etc.

Installation method: Horizontal or vertical

Product Characteristic:

1?Body use excellent forge steel, ensure there has no holes, cracks etc quality problems.

2?Good corrosion resistance.

3?Double block and bleed function, the upper and lower side of seat make fluid block, body retaining discharge through discharge valve.

4?Fire safe construction

5?Open close quickly and convenient

6?Compact structure, light weight, small height direction.

7?The spherical closing part can automatically locate on the boundary position, and can withstand the high pressure difference when closing.

8?When fully open and fully closed, sealing face of the ball and seat isolated from medium

9?Having a rotary movement of 90 degrees, the ball has a circular through hole through the axis, full bore ball cavity reduces the medium resistance, increase the flow channel

10?Valve ends can add pipes

11?Can buried use, stem can add according to project requirements, put the corresponding grease, sewage and venting device consists of a tube extended to the ground.

Working Principle:

Application:

It applies to: chemical, petroleum, natural gas, metallurgy, and other industries and hydrogen sulfide-containing media, impurities, corrosion serious long distance gas pipelines.
