Butt Welding Gate Valve, also known as Butt Welding gate valve, is a valve used to control fluid flow, widely used in petroleum, chemical, natural gas and other industries. It realizes the function of opening or closing the pipe by lifting the ram. The following are some features and related information of butt weld gate valves:

Advantages: The butt welding gate valve has the advantages of small fluid resistance, small erosion and erosion of the sealing surface by the medium, less effort to open and close, the medium flow direction is not restricted, no disturbing flow, no reducing pressure, simple shape, short structural length, good manufacturing process and wide application range.

Disadvantages: However, it also has some disadvantages, such as easy to cause erosion and abrasion between the sealing surface, maintenance is more difficult; The overall size is large, the opening needs a certain space, and the opening and closing time is long; The structure is more complex.

Types: There are various types of butt welded gate valves, which can be divided into wedge gate valves and parallel gate valves according to the sealing surface configuration. Wedge gate valve can be divided into single gate, double gate and elastic gate. According to the thread position of the valve stem, it can be divided into two kinds: open stem gate valve and dark stem gate valve.

Installation and maintenance: When installing and maintaining the butt weld gate valve, it should be noted that the handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited. The double gate valve should be installed vertically, and the gate valve with bypass valve should be opened before opening to balance the pressure difference between the inlet and outlet and reduce the opening force. If the valve is used frequently, lubricate it at least once a month.

API 600 Standard: The API 600-2021 standard specifies requirements for steel gate valves used in refineries and related applications for corrosion, erosion and other operating conditions, including flanged and butt welded ends, bolted caps, etc.

Purchase and inquiry: If you need to purchase butt welded gate valves, you can contact manufacturers in China through B2B platforms such as Made-in-China.com. You can ask for a minimum order and request a quote by filling out a short web form.

Manufacturer Information: XINTAI Valve specializes in the manufacture of high quality valves for the global oil, gas, industrial and machinery markets, and has passed ISO9001 quality management system certification.

The above is some basic information about the welding gate valve, if you need more detailed technical parameters or have specific purchase needs, it is recommended to contact a professional valve manufacturer or visit the relevant industry website for more information.
