Duplex Stainless Steel Gate Valves
All these valves are available with below connections. However, the corrosion resistance of the least resistant Duplex stainless steel is greater than that for the most commonly used grades of stainless steel, i. e. 304 and 316. There are 4 types of check valves we are familiar in the site. Alloy 410 is a general purpose stainless steel with 12% chromium martensitic properties. No limitation on the flowing direction of the medium. J-Valves is a leading China duplex stainless steel ball valve manufacturer, supplier and exporter. WhatsApp: +86 185 1656 9221. Your local business too needs brand management and image making. Super Duplex Steel: ASTM A890/A995 6A, Duplex 2507. They are not quite as easily welded as the austenitic grades but low thermal expansion in duplex grades reduces distortion and residual stresses after welding. The yoke is heavy duty cast carbon steel or cast stainless steel for additional corrosion resistance. FBV globe valves are offered in straight pattern, bolted bonnet and welded bonnet design in a wide range of carbon, stainless steel, duplex stainless steel, alloy and other special materials. Desalination plants are typically located offshore places where the air can be very humid and corrosive.

Duplex Stainless Steel Gate Valves Types
End Connection according to ASME B16. Type 410 is made for working with a variety of liquid and gaseous substances because of its hardness and corrosion-resistant composition. Duplex Steel Valves: Ball Valves, Gate Valves, Globe Valves, Check Valves. Compared with 316L and 317L austenitic stainless steel, duplex stainless steel 2205 alloy has superior performance in pitting corrosion and crevice corrosion. Due to the presence of austenite, duplex stainless steel reduces the brittleness of high-Cr ferrite and the tendency of crystal growth, while maintaining excellent toughness and welding performance; while the presence of ferrite increases the yield of austenite Strength, resistance to intergranular corrosion, and chloride stress corrosion resistance. Gate valve is a linear type on/off valve, but the ball valve is a rotary type on/off valve. Lift Check valves are suitable for installation in horizontal or vertical pipelines with upward flow. Media: Oil, Gas, Chemical, Process Industries, Water. Weidouli is a valve maker that can offer Duplex gate valves with different features, contact us to know more! Applications: Neutral chloride environment\refining industry\petrochemical and chemical industry\chemical industry pipelines\oil and gas industry\pulp and paper industry\chemical fertilizer industry\urea industry\phosphate fertilizer industry\seawater environment\energy and environmental protection industry\light industry And food industry\food and pharmaceutical industry equipment\high-strength structure.

Alloy 410 is available through Sandmeyer Steel Company in thicknesses from 3/16" up to 4".
Duplex Stainless Steel Gate Valves Manufacturers
At low temperatures duplex stainless steels have better ductility than the ferritic and martensitic grades. 96 Fanhua East Road, OuBei, WenZhou, Zhejiang, China, 325102. Features: Duplex stainless steel ball valves are more and more popular used for high corrosion applications. Duplex grades can readily be used down to at least -50°C. One-piece Ball Valves. To achieve optimal performance, usually will use a lever and weight hammer or a lever with springs to quickly close the valve. Manufacturer and supplier of industrial valves, including Floating Ball Valves, Trunnion Ball Valves, Flanged Gate Valves, Welded Gate Valves, High Pressure Gate Valves, Globe Valves, Swing Check Valves, Double Disc Wafer Check Valves, Y Strainers, etc.
Stainless Steel Flanged Gate Valves
Even in chloride and sulphide environments, Duplex stainless steel exhibit very high resistance to stress corrosion cracking. Butt Weld, Socket weld, Threaded, Flanged. Duplex stainless steel is also known as S31803, S32205, A351 CD3MN, ASTM A182 F51 and 1.
Duplex and aluminum bronze self-operated pressure regulators. If you are interested in our products, please click on the following PDF file name to open the Ctrl+S or the right mouse button to save your equipment. We train our technicians from time to time to master the professional technical knowledge to guarantee the quality of our 4-Way Stainless Steel Ball Valve, High Pressure Trunnion Ball Valve, Side Entry Trunnion Mounted Ball Valve. Nowadays dual plate check valves are widely used in Power Plants, Refineries, Chemical Plants, Wastewater Treatment Plants and Pulp & Paper Mills. Operator: Lever/ Gear Box/ Actuator.
• UNS ASTM A276 S31803 / S32205. It has high corrosion resistance. At the opening position, the swing type check valve offers very little resistance to the flow. Stainless Steel Plate. Maintenance of Globe valves is relatively easy, as the discs and seats are readily refurbished or replaced. • Oil and gas exploration and offshore rigs, as well as refining. Do you have a minimum order quantity (MOQ) limit? Standard connections. Ni||Cr||Mo||Mn||Si||C||N||S||P||Fe|. Ball valve has excellent performance of tight sealing than gate valve, and are way less prone to leakage. End Connection Type: Flange End, Socket Weld, Butt Weld End, Screwed, Etc. Lift Check valves are particularly suitable for high-pressure service where the velocity of flow is high.
Small flow resistance for fluid, only a small force is required when opening and closing. The principle of the check valve is working on differential pressure, it means the check valve only opens if the inlet pressure is over the outlet pressure. ▤ Production R&D & Own Factory. 4 Bolt: A193 B16 Gasket: Stainless Steel+Graphite Backseat: A182 F51, F53, F55 Bonnet: A890 4A, A890 […]. 5 (RF & RTJ), ASME B16. As an example, machining of 2205 is around 20% slower than for 304. DBV can produce valves with various end connection, such as RF, RTJ, BW, NPT, Rasied Face is the most common type used in process plant applications.
