All Welded Ball Valve

All-welded ball valve is a new kind of new energy-saving truncation valve researched and developed in our factory by introducing foreign advanced design technology and equipment. Due to its special structure, novelty, utility, light weight, small material consumption, it is a kind of very good energy conservation and environmental protection product in today's environmental protection and energy saving economical situation. The feature is when the valve closes, the internal leakage can achieve zero leakage, it can reduce the loss caused by energy loss to the lowest point, which greatly improves the energy saving and fluid measurement accuracy. It solves the phenomenon of "escape, emit, drop, leak" existed in all delivery systems, thus greatly improves the safety, reducing the expenses for maintenance use, providing convenience to the users.

This valve is one of the most ideal block valves applied to industries like urban heating, city gas, natural gas pipeline, chemical industry, power, light industry, food, textile etc. After years of market tests, the product quality reaches the same level of similar products abroad. So it has a good reputation among the users.

Application

City Gas: Gas output pipelines, trunk and feeder supply lines etc.
Central heating: large heating equipment output pipeline, trunk and feeder
Heat exchanger: opening and closing of the pipes and the loops
Iron and steel plant: all kinds of fluid pipes, exhaust pipes, gas and heat supply pipelines, the fuel    supply lines
All kinds of industrial equipment: all kinds of heat pipes, industrial gas and heat distribution pipelines

Features

Integral welded ball valve doesn't have external leakage phenomenon.

The valve seat is composed by carbide Teflon seal ring and belleville spring, so it is adaptable for the change of pressure and temperature. It won't produce any drainage within the marked range of pressure and temperature.

The machining process of sphere is traced and checked by advanced computer detector, so the sphere has high machining accuracy.

The valve body material is the same as pipe material, so there will be no unbalanced stress, and it won't distort due to earthquake and the vehicle going through the ground. The pipe has resistance to aging.

Sealing ring uses RPTFE material with 20% Carbon, which ensures no leakage.

Directly buried type welded ball valve can be directly buried underground, people don't have to build a high large valve well, they only need to set up small shallow wells in the ground, which greatly saves the construction cost and the project time.

According to the demand of pipeline construction and design, people can adjust the length of the body and the height of the valve stem.

The machining precision of sphere is very precise, convenient operation, no harmful interference.

Service life more than 15 years in the event of normal operation and usage of the valve.
