End Connection Type: Flange End, Socket Weld, Butt Weld End, Screwed, Etc. One of the key conditions of the check valve is at the pump downstream to protect the expensive and important equipment from flow reversal. Duplex stainless steels have stronger resistant to corrosion than the commonly used grades of stainless steel valves, namely 304 valves and 316 valves.

We take customer demand as the guide, technical service as the center, and customer satisfaction as the goal to comprehensively improve the strength of our company in the field of Super Duplex Stainless Steel Gate Valves. If you need it one day in the future, we do appreciate it for your kindness. Class 150 to Class 2500. Dual plate check valves are suitable for liquid, gas, steam, condensate, water supply, oil & natural gas services. A Good Partner Is A Lasting And Effective Investment. Duplex stainless steels are in most cases, tougher than ferritic stainless steel. And our engineers work tirelessly to innovate and improve. Do you have a minimum order quantity (MOQ) limit?
Duplex 3 Piece Ball Valve. Duplex alloys are nearly equal in strength to the C276 and AL6XN alloys. Carpenter 20Cb contains columbium and tantalum. Whilst duplex stainless steels are considered resistant to stress corrosion cracking, they are not as resistant to this form of attack as ferritic stainless steel. End Connection according to ASME B16. Anti-Extrusion Ring and many packing material options to meet the demands of your specific application. Tell us more about your requirements so that we can connect you to the right service provider. Bolted Bonnet or Pressure Seal Bonnet. 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. Oil and gas refining. Outside Screw & Yoke (OS&Y), Rising stem. In lift Check valves, the disc is precisely guided and fits perfectly into the dashpot.
Duplex Stainless Steel Gate Valves Vs
D10079 - IM ACT MANUAL GATE VALVES. Both of these two methods will challenge our valves should meet corrosive environment, high salinity media, and cavitation. The high chromium content of Duplex stainless steel that protects against corrosion, causes embrittlement at temperatures over about 300°C. D11015 - IM VALVE KGC 22", 26"-48" ES OR HD. 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. Gate valve is a linear type on/off valve, but the ball valve is a rotary type on/off valve. Applicable Medium: Water/ Oil/ Gas/ Chemical/ Petrochemical. The check valves are very common to use for industrial pipelines.

The principal variation in Globe-valve design is in the types of discs employed. Wenzhou Duplex stainless steel gate valve.
Stainless Steel Knife Gate Valves
Notice how the valve slices through the dry material. Your local business too needs brand management and image making. 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. Type 410 is made for working with a variety of liquid and gaseous substances because of its hardness and corrosion-resistant composition. Devices like Heat exchanger and condensator. Media: Oil, Gas, Chemical, Process Industries, Water. No limitation on the flowing direction of the medium. The properties and composition of the gate valve material is very important, especially since they are required to carry a range of liquids or gases that could affect certain substances. The valve will close when the inlet pressure decreases below the cracking pressure or there is backpressure.
It not only has austenite plus ferrite bidirectional structure, but also saves Ni alloy. Duplex steel valve manufacturer and supplier. Bare shaft/ positioner/ limit switch box. For metal seated ball valves, size from 1/2" to 2", the MOQ is 5 pieces, and size from 3" to 4", the MOQ is 3 pieces. Matching Knife Gate with rounded edges. Nowadays dual plate check valves are widely used in Power Plants, Refineries, Chemical Plants, Wastewater Treatment Plants and Pulp & Paper Mills. They provide excellent hydrodynamic properties that result in very low-pressure losses and they are technically efficient.
