Compared with 316L and 317L, the designer can reduce its weight. Chemical process plant. Duplex stainless steels are in most cases, tougher than ferritic stainless steel. KGC-ES Extended Service Life Cast Stainless Steel Knife Gate Valves 35. Duplex alloys are in a class with several other materials for various types of corrosion resistance. Adhering to the pursuit of perfect quality of products, so that our duplex stainless steel ball valve have been satisfied by many customers. Next: ASTM A890 5A Gate Valve, 10 Inch, 150 LB, RF, API 600, ASME B16. The principal variation in Globe-valve design is in the types of discs employed. Duplex stainless steel has the advantages of both ferritic stainless steel and austenitic stainless steel: austenitic stainless steel reduces the brittleness, maintains excellent toughness and weldability; ferritic stainless steel improves the yield strength, intergranular corrosion resistance and chloride stress corrosion resistance. Main Material: Super Duplex. Duplex stainless steel have good weldability. Duplex stainless steels are also magnetic, a property that can be used to easily differentiate them from common austenitic grades of stainless. We adhere to the mission of 'making products intelligent and service intimate'. Face to Face: ASME B16.

Duplex Stainless Steel Gate Valves How To

We continuously improve production efficiency, stabilize product quality and participate in primary maintenance, reduce production line downtime. A check valve allows flow in one direction and automatically prevents back flow (reverse flow) when fluid in the line reverses direction. The microstructure of the duplex stainless steel valve consists of a mixture of an austenitic phase and a ferrite phase. Chemical composition: C≤0. Under strict restrictions (especially for welded structures), it can also be used at lower temperatures. Duplex Valve Avaliabe In Stock - Fast Delivery. Flanged, threaded, socket weld or combination.

Stainless Steel Water Supply Gate Valve

Ball: Duplex Stainless Steel, CF8, CF8M, Cast Iron, Carbon Steel 4. For soft seated ball valves, size from 1/2" to 4", the MOQ is 6 pieces. Alloy Valve Stockist generally stocks super duplex A182 F51 and A890 Gr. With us your money in protected your business enterprise in secure. Those in the oil and gas, pharmaceutical, water and waste water treatment, infrastructure and dam gates, or marine industry, looking for the right material for an effective gate valve, can look no further than Sandmeyer Steel. The elements that provide the strength and corrosion resistance in duplex are much more common than those found in some high-nickel alloys. The check valves are very common to use for industrial pipelines. 2 Way Valve Shear Gate Valve Gate And Globe Valve Flowserve Gate Valve. The stem is stainless steel.

Tooling and work surfaces must be thoroughly cleaned before use. The manual regulating valve can be used for oil refining. Optional 30°, 60°, and 90° V-Port ball for regulating the flow. Duplex stainless steel valves are extremely corrosion resistant. Duplex Floating Ball Valve 1. A nozzle check valve is a kind of non slam check valve, which is specifically designed for non slaming when valve closing and preventing excess pressure. Duplex stainless steels have stronger resistant to corrosion than the commonly used grades of stainless steel valves, namely 304 valves and 316 valves. Heat Treatment of Duplex stainless steel. 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. Stem extended design can be chosen. Copyright © 2017 Baltic Valve Co., Ltd. All rights reserved. This is why Alloy 410 is an ideal choice. Even in chloride and sulphide environments, Duplex stainless steel exhibit very high resistance to stress corrosion cracking.

Duplex Stainless Steel Gate Valves Types

Its PREN value of UNS S31803 is between 38 to 45. Face-to-face according to ASME B16. The desalination process, especially the seawater reverse osmosis system(SWRO), requires a large number of valves that can treat large amounts of water under high pressure. Nut: A193-B8 Nominal Size: DN15 to […]. Application: Gate valve is a kind of on/off valve used in the pipe system. The lower nickel and molybdenum content of the Duplex Stainless Steels as compared to the austenitic grades with similar corrosion resistance, gives the Duplex grades a lower cost. DP00129 - IM ACT DYNATORQUE BEVEL GEAR KNIFE GATE.

Stainless Steel Gate Valves

Gate valve is at lower costs than a ball valve. 5 (RF & RTJ), ASME B16. Other body, gland and gate materials are available upon request. Do you have a minimum order quantity (MOQ) limit? Gate valves should only be used to permit or prevent the flow, not to regulate flow speed, as the valves are typically designed to be fully opened or closed. Lift Check valves are suitable for installation in horizontal or vertical pipelines with upward flow. Alloy 410 Stainless Steel Properties and Composition. Lift Check valves are particularly suitable for high-pressure service where the velocity of flow is high. Stem: SS304, SS316 5. Oil and gas exploration and offshore rigs.

Oil and gas refining. Category: Gate, globe, and check valves. Many standard body, packing gland options are available including 304, 316, 317, 254-SMO, 2205 Duplex Stainless Steel, Hastelloy C 276. Duplex and super duplex stainless steel ball valves.

Due to excellent corrosion resistance and high strength, the most widely used duplex stainless steel is 2205. Both of these two methods will challenge our valves should meet corrosive environment, high salinity media, and cavitation. Pressure Rating: CIass150-2500Lb, 1. Applications of Duplex stainless steel. Duplex alloys are nearly equal in strength to the C276 and AL6XN alloys. Alloy 410 is available through Sandmeyer Steel Company in thicknesses from 3/16" up to 4". Specifications (English). Bare shaft/ positioner/ limit switch box. For more information, please send us your email. A: Usually, the term is "Ex-Works". As an example, machining of 2205 is around 20% slower than for 304.

Machining can be enhanced by using the following rules: Welding of Duplex stainless steel. And multi-stage flashing (MSF) is processes flash water (boils by means of pressure reduction) over several stages to separate freshwater from concentrated brine. 4A gate, globe, check, ball, butterfly, plug, needle and custom made valves. Full Bore or Reduced Bore.

Cap: CF8, CF8M, Cast Iron, Carbon Steel 3. In lift Check valves, the disc is precisely guided and fits perfectly into the dashpot. This combination of properties can mean some compromise when compared with pure austenitic and pure ferritic grades. D10079 - IM ACT MANUAL GATE VALVES.
