Full diameter full welding ball valve

Dateline:2014-11-30    Hits:


Full welded ball valve, there will be no external leakage.

Because the seat is made of carbonized teflon seal ring and disc spring form, so thechanges in the pressure and temperature of the strong ability to adapt, not in theannotation of pressure and temperature range to produce any discharge slide.

The machining process of sphere has detector advanced computer tracking and detection, so the machining precision of the high sphere.

As the valve body material and pipe material, won't appear the stress is not uniform,will not because of the earthquake and the vehicle through the ground from generating deformation, pipelines aging.

The sealing ring body with contents of 25%Carbon (Tan Su) RPTFE material, ensureno leakage (0%).

Buried welded ball valve can be directly buried underground, don't build high largevalve well, just set small shallow wells in the ground, save construction cost andconstruction time.

According to the construction and design requirements of the pipeline, adjust thebody length and the stem height.

The machining precision of sphere is very precise, easy operation, no harmfulinterference.

Raw materials used in advanced, can guarantee the pressure more than PN25.

Compared with similar industry with the same specification product body is small, andthe appearance is beautiful.

In normal operation, to ensure that the valve use case, life in 15 years.
