Globe Valve

SGON Cast steel globe valves is used for throttling flow control. Shut off is accomplished by moving the disc against the flow stream rather than across it as in the case with a gate valve. The flow pattern through a globe valve involves changes in direction,resulting in greater resistance to flow,causing high pressure drop. SGON Cast steel Globe valves is an excellent valve to use for on-off service,also is highly suited for frequent cycling and control of fluids anywhere in amount or volume between the open and closed positions.

SGON Stainless Steel Globe Valves is a kind of cut-off valve. The material requirements of the valve body are higher than that of 301.304.316 and other materials, which are widely used in chemical industry, ship, medicine, food machinery and other industries. The valve stem axis of the globe valve is perpendicular to the sealing surface of the valve seat. The opening or closing of the valve stem is relatively short, and has a very reliable cutting action, making the valve very suitable for cutting or adjusting and throttle use of the medium. The closing principle of the globe valve is to close the valve sealing surface and the valve seat sealing surface by means of the pressure of the valve bar to prevent the circulation of the medium.

The Pressure Seal Globe Valves is only suitable for full opening and full closing, and no adjustment and throttling are allowed. The globe valve is a forced seal valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve under the valve, the resistance that the operating force needs to overcome is the friction force of the stem and the filler and the thrust of the pressure from the medium. The force of the valve is larger than that of the valve, so the diameter of the stem is large, otherwise the valve rod will have the failure of the top bending.

SGON Cryogenic Globe Valves are designed and manufactured strictly to International Standards BS 1873, ASME B16.34 or DIN3202, During the processes of production, transportation, storage and usage of liquefied gases, countless technical problems can be experienced. Med cryogenic Globe valves are designed to assure safety and reliability under these critical conditions. All of Med cryogenic Globe valves are thoroughly cleaned and decreased. Afterwards the end ports are sealed to prevent contamination. This process is performed in an approved and designated clean room.

The Y Pattern Globe Valves is only suitable for full opening and full closing, and no adjustment and throttling are allowed. The globe valve is a forced seal valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve under the valve, the resistance that the operating force needs to overcome is the friction force of the stem and the filler and the thrust of the pressure from the medium. The force of the valve is larger than that of the valve, so the diameter of the stem is large, otherwise the valve rod will have the failure of the top bending.

The Cast Bronze Globe valves is suitable for cutting or connecting the medium on the pipelines of various working conditions, such as ANSIClass150 ~ 2500Lb, oil, chemical, thermal power station and so on at the working temperature of less than 600. The suitable medium is water, oil, steam and so on. The operation modes are manual, gear drive, electric, pneumatic and so on. Metal ring gasket is adopted for sealing, high strength, reliable sealing and good durability.

SGON Angle Type Globe Valve is a new type of globe valve. Because the valve is double seal design, its sealing performance is more reliable than that of common cut-off valve. The metal barrier formed by the bellows can prevent leakage. The packing can also provide a seal after the failure of the bellows. It can be used more safely, energy saving, environmental protection and zero leakage. More than DN150 products, adding triangle positioning device, effectively prevent the valve in the use of trembling, noise, and cause damage to the inner parts, the service life effectively increased by more than 150%. The valve body is made of German coated sand casting technology, which greatly improves the surface smoothness and mechanical properties of the valve body, reduces the appearance of holes, sand holes and cracks, and strengthens the tensile strength of the castings. Products are used in steam system, heat transfer oil system, cold and hot water system, etc.

SGON Bellows sealed globe valve introduced advanced foreign technology, using double bellows design, welded to the valve stem to maintain stable operating performance, avoid the valve vibration caused by valve plug vibration. At high temperature, the stem does not touch the medium to ensure zero leakage of the stem. At the same time ensure enough strength and toughness, can switch tens of thousands of times. The handwheel is ergonomically designed, with longer service life and easy and convenient operation. The opening and closing of the bellows cut-off valve is a plug shaped valve. The seal face is flat or cone, and the valve is moving straight along the center line of the fluid. It is the most widely used valve. It is popular because of the small friction between the sealing surfaces in the process of opening and closing, which is relatively durable, the opening height is small, the manufacturing is easy, and the dimension is easy to make. It is convenient not only for medium and low voltage but also for high voltage. Widely used in food, medicine, petroleum, chemical industry, natural gas, iron and steel, environmental protection, papermaking and other transportation pipelines to cut off or circulate medium.

The stop valves opening and closing part is a plug-shaped disc. The sealing surface is flat or conical. The disc moves linearly along the center line of the valve seat. The movement form of the valve stem can also be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. This type of shut-off valve is very suitable for shut-off or regulation and throttling. Because the opening or closing stroke of the valve stem is relatively short, and it has a very reliable cut-off function, and because the change of the valve seat opening is directly proportional to the stroke of the valve disc, it is very suitable for regulating the flow.

The Investment Casting Screwed Globe Valves stem axis of the shut-off valve is perpendicular to the sealing surface of the valve seat. The opening or closing of the valve stem is relatively short, and has a very reliable cutting action, making the valve very suitable for cutting or adjusting and throttle use of the medium. The structure is simpler than the gate valve, and it is more convenient to manufacture and maintain. The sealing surface is not easy to wear and scrape, and the seal is good. There is no relative sliding between the valve and the sealing surface of the valve body during the opening and closing. Therefore, both the wear and the abrasion are not serious, and the sealing performance is good and the service life is long.

SGON Forged Steel Globe Valves is a common cut-off valve, mainly used to connect or cut off the medium in the pipeline, generally not used to regulate the flow rate. The cut-off valve is suitable for the pressure and temperature range. This valve is suitable for small diameter pipes. The sealing surface is not easy to wear and scrape. The sealing performance is good. When the valve is opened and closed, the valve stroke is small, the opening and closing time is short, and the height of the valve is small.
