1. Fluorine-lined globe valve
Fluorine-lined valve, also known as fluoroplastic lined corrosion-resistant valve, is a method of placing polytetrafluoroethylene resin (or profile processed) on the inner wall of a steel or iron valve pressure-bearing part (same method) by molding (or inlaying). It is suitable for the lining of various pressure vessels and pipeline accessories) or the outer surface of valve internals, and is made into various types of valves and pressure vessels by using its unique properties in resisting strong corrosive media. With the rapid development of modern industry, fluorine-lined valves and their various pipeline accessories have been rapidly applied and promoted in various fields such as petroleum, printing and dyeing, and chemical industry, showing strong vitality. Great attention and favor of units and construction units, it is a sunrise product with great market potential.
The fluorine-lined globe valve is suitable for various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids and strong oxidants at various concentrations of -50 to 150 °C. It is also suitable for use in pipelines with various concentrations of strong alkali organic solvents and other corrosive gases and liquid media.
2. National standard globe valve
The national standard globe valve is the most commonly used product in the globe valve series. The API American standard globe valve implements ANSI and API standards. The sealing surfaces of the disc and valve seat are made of stellite cobalt-based carbide with different hardness. Reliable, high hardness, wear resistance, high temperature resistance, corrosion resistance, good scratch resistance, long life. Needle valve is a small diameter instrument valve, which plays the role of opening and closing and accurate flow control in the instrument measurement pipeline system, mainly including power station instrument series, oil field special series, American standard series, etc.
3. Welded needle globe valve
Cryogenic globe valves usually refer to valves whose working temperature is lower than -110°C, and are widely used in liquefied natural gas, liquefied petroleum gas and other low temperature industries. At present, globe valves suitable for temperatures up to -196°C can be manufactured, and all parts are pretreated with liquid nitrogen at low temperature to completely avoid seal deformation and leakage during use. MstnLand is a professional globe valves supplier which has our own globe valve factory. We can provide various high quality globe valves.
4. Plunger globe valve
The sealing surface of the plunger valve adopts a radial sealing structure, and the elastic sealing ring around the plunger is compressed by the load exerted on the valve cover by the two elastic sealing rings sleeved on the polished plunger through the connecting bolt of the valve body and the valve cover.
5. Insulation jacket globe valve
The design of thermal insulation jacket is adopted, and the external heat source is used to circulate heating outside the valve, which can effectively prevent the temperature loss of the medium when passing through the valve, and ensure the temperature of the medium.
6. Forged steel globe valve
Forged steel globe valve is designed and manufactured in accordance with API 602 standard, and provides three types of bonnet designs: bolted bonnet, welded bonnet, pressure self-tightening sealing bonnet, users can choose different forms according to their needs, providing RF flange, There are three connection methods: NPT thread and SW welding.
7. Oxygen special globe valve
Oxygen special globe valve is made of high-quality silicon brass or stainless steel, which has the advantages of high mechanical strength, wear resistance and good safety. Used on oxygen pipelines, it has the best explosion-proof and flame-retardant performance, eliminating the unsafe factors on oxygen pipelines, and is widely used in the pipeline network of steel, metallurgy, petrochemical, chemical and other oxygen-using projects. In addition to the functions of ordinary valves, it also has its own characteristics. Strict oil-free measures are adopted during manufacture, and all parts are strictly degreased before installation.
8. Bellows globe valve
The bellows globe valve is designed with formed stainless steel bellows. The bellows reciprocates 10,000 times without failure, and the sealing performance is reliable. It is suitable for the working conditions of flammable, explosive, toxic and harmful media, and can effectively prevent the valve from leaking.
