Several categories of valve products in China


The domestic market valve manufacturers about more than 2300, can provide the valve products have several categories, more than 3500 varieties, more than 40,000 specifications. Here is an introduction to the classification of valves!

Brief description of the classification and structure of ball valves


Ball valves are divided into: floating ball ball valves, fixed ball ball valves, orbital ball valves, V-shaped ball valves, three-way ball valves, stainless steel ball valves, cast steel ball valves, forged steel ball valves, ash discharge ball valves, sulphur resistant ball valves, pneumatic ball valves, electric ball valves, ferrule ball valves, welded ball valves.

Ball valve maintenance precautions


If a slight leak occurs at the packing, the stem nut must be locked again. But do not lock too tight, usually lock again 1/4 turn ~ 1 turn, the leakage will stop.Second, replace the valve seat and seals

Advantages of electric valves over traditional valves


In terms of operational efficiency and energy savings, the use of automatic control valves is an indispensable part of the process. The manual and pneumatic valves traditionally used in industry are not as cost effective as electric valves in terms of installation and efficiency.

Advantages and disadvantages of pneumatic and electric valves


Pneumatic valve action force distance than the electric valve, pneumatic valve switch action speed can be adjusted, simple structure, easy maintenance, action process because of the gas itself buffer characteristics, not easy to damage due to jamming, there is a gas source, and its control system is also more complex than the electric valve.

How to choose the right electric ball valve


According to the introduction, in the next 10 years, China will have more than 20,000 kilometres of oil pipelines to be built, including Russia, Kazakhstan and other transnational oil pipelines. In addition, following the "West-East gas transmission", China will have to build more than 20,000 kilometres of transnational gas pipelines and branch lines.
