ST ball valve is divided into floating ball valve and trunnion mounted ball valve, the matrix material is mainly carbon steel, stainless steel, duplex steel, aluminum bronze.There are soft seals and metal hard seals;Three types of body construction: flange, top and all welded.
Widely used in petroleum, long pipeline, chemical industry, papermaking, pharmacy, water conservancy, electric power, steel and other fields, suitable for a variety of corrosive and non-corrosive media, can be used to transport water, steam, oil, natural gas, nitric acid oxidation medium, urea, etc.

ST gate valve, divided into wedge gate valve, flat gate valve, parallel double gate valve, wedge double gate valve;Wedge gate valves are divided into open stem gate valves and dark stem gate valves, and double of wedge and wedge valves.
Different materials can be used in water, steam, oil, nitric acid, acetic acid, oxidation medium, urea and other media.
Driving mode: electric, pneumatic, manual, pneumatic, hydraulic and so on.The connection mode is flange type, welding type, clamping type.

ST globe valve is mainly BS1873 globe valve and forged steel globe valve, can meet the United States, Russia, Germany and other standards.
It is used for cutting off or regulating and throttling of water, sewage, construction, food, electric power, medicine, metallurgy, light textile, energy and other fluid pipelines.
Globe valves are usually flanged or welded.
Optional driving device: handwheel, bevel gear, electric, pneumatic and so on.

ST mainly swing check valve and lift check valve, and double plate type check valve
Its main role is to prevent the backflow of media, to prevent the pump and its drive motor reversal, and the release of media in the container.It may also be used to supply an auxiliary system whose pressure may be higher than that of the system.
The connection can be divided into threaded connection, flange connection, welding connection and clamping connection.

ST butterfly valve has center line butterfly valve, double eccentric butterfly valve, triple eccentric butterfly valve;Soft seal and hard seal.
Butterfly valve is suitable for the transmission of natural gas, natural gas, liquefied petroleum gas, hot and cold air, chemical smelting and power generation environmental protection, building water supply and drainage engineering system in a variety of corrosive and non-corrosive fluid medium.
