Hard Seal Forged Steel Ball Valve DN15~DN350

Hard Seal Forged Steel Ball Valve This kind of ball valve is divided into two forms: . One is the two-piece structure with the screw threaded connection and sealed with PTFE gasket; The other is the triplet structure with the bolt in the middle. According to the different valve seat, gasket and padding, the working temperature and media are diversified. Feature: Overall diameter/reduced diameter 90 degree and with key structure With Y Handle Fire prevention and anti-static

QYB process instrument hard seal ball valve

To solve the problem that the small-bore process or gauge valve for common industry is short-life, has independently developed a metal hard seal ball valve with patented technologies. This valve series adopts world advanced and unique technologies for its design in structure, sealing surface treatment and external leak point so that it not only is applicable for high temperature (760℃) and high pressure (1,000Mpa) but also has an excellent

Floating seat ball valve

ball valve can be designed into a soft or hard seal structure as required by working conditions or users. With its unique hard surface treatment technology, hard seal V-type ball valve is more applicable for media containing impurities. Its reasonable flow channel design prevents materials from accumulation. According to practical working conditions, can provide the floating seat V-type ball valve and the eccentric V-type ball valve.

pneumatic-hydraulic metal hard seal ball valve

QYIII series metal seal ball valve adopts a fixed ball structure, which conforms to relevant standards strictly regarding its design, material selection, manufacturing test, surface treatment and painting. There are multiple options for materials of its internal components, subject to application in working conditions. It is optional for full or reduced bore and also for many kinds of actuators, which is an ideal valve option for chemical engineering, petroleum refining,

butt-weld metal hard seal ball valve

QYII metal hard seal ball valve is widely applied in extremely harsh working conditions, like the catalyst in the coal chemical industry, poly-silicon and oil refining, and the abrasion-resistance valve in the mine industry. As for the two/three-phase flow (pneumatic/solid/hydraulic) working condition, we’ve developed the self-cleaning seat with the patent design and the damping sediment structure, which have been applied successfully in major national projects.
