Product description

     Large-caliber full-bore ball valves are suitable for use in the pipelines of various working conditions such as petroleum, chemical, thermal power plants, etc., with a working temperature of -29～200℃, Class 150～300Lb, to cut off or connect the medium. Applicable media are: petroleum, purified natural gas, sour natural gas, coal gas, water, coal slurry and other media. The operation modes are: worm gear drive, pneumatic, electric, gas-liquid linkage.

Scope of application

       City gas: gas output pipeline, main line and various branch supply pipelines, etc. Centralized heating: output pipelines, main lines, and branch lines of large-scale heating equipment. Heat exchanger: the pipeline and each circuit are opened and closed. Iron and steel plants: various fluid pipelines, exhaust gas discharge channels, gas and heat supply pipelines, fuel supply pipelines, etc. All kinds of industrial equipment: all kinds of heat treatment pipelines, all kinds of industrial gas and heating pipelines.

Product Features

       The large-diameter full-diameter ball valve adopts a fixed ball structure. The upper and lower shafts of the ball are equipped with bearings, and the operating torque is small. The ball of this structure is fixed and does not move after being compressed. It is designed with two sealing rings to provide enough The pre-tightening force guarantees the sealing, and achieves the double-sided forced sealing, and the sealing performance is more reliable. The processing process of the sphere is tracked and detected by an advanced computer detector, and the processing precision of the sphere is high. Since the valve body material is the same as the pipe material, there will be no uneven stress, and no deformation due to earthquakes and vehicles passing the ground. The sealing ring body is made of PTFE material with a content of 20% C (carbon), which guarantees no stress. Leak (0%).
