Mounting of Body Seat Rings Bonnet Gasket Materials Body seat rings of KITZ cast steel valves are mounted on the valve body by seal welding as shown in the typical examples of gate valves illustrated below. Unless specifically requested in advance, mounting of body seat rings shall be made at the manufacturer's discretion. Cast or Forged? - Valve MagazineThe good news is that both types of valves should be able to provide you with acceptable performance, although a perception exists that forged valves are superior to cast valves. However, if cast valves are made properly, they can and have worked equally well in a variety of services and usually at a much lower cost than forged valves. Also, the belief that forged components are infallible is China Rohs Brass Material, China Rohs Brass Material China Rohs Brass Material, China Rohs Brass Material Suppliers and Manufacturers Directory - Source a Large Selection of Rohs Brass Material Products at brass honey scrap ,valve brass ,brass copper bathtub from China
Cobalt-chromium Alloy 6 is a very popular material for hard valve trim in applications requiring resistance to sliding wear, erosion and/or cavitation. Its even successfully used in applications that are somewhat corrosive. However, in some areas of boiler feedwater applications where it would seem Alloy 6 should perform well, problems have been encountered. Gate, Globe & Check Valves Stainless Steel & High AlloyThe original casting technology used, which includes casting simulation, Slag Refining Process (SRP) and state of the art Exotic Material Furnace (EMF) heat treatment, makes KITZ the premier stainless and special alloy valve manufacturer. How To Select Valve Materials Winning Fluid EquipmentFor this reason, cast carbon steel is the most commonly used valve body material and can provide satisfactory service at much lower cost than the exotic alloy materials. Some commonly used carbon steel materials for valve body are WC steel (Wrought Carbon), ASTM A216/A216M and A105 as the forged version of this steel with grades WCA, WCB and WCC.

Body - 316 cold worked stainless steel; Packing Marking of Steel Pipes, Steel Flanges, Butt Weld Fittings Each valve shall have a corrosion-resistant metal identification plate with the following information:- Manufacturer - Manufacturer's model, type, or figure number - Size - Applicable pressure rating at 100F - Body material - Trim material; Valve bodies shall be marked as follows:- Threaded-end or Socket Welding-end valves - 800 or 1500 Properties and Applications of Ni-Resist and Ductile Ni alloys and the ductile or spheroidal graphite alloys. Except for the copper containing ones, the groups have materials similar in composition but for a magnesium addition which converts the graphite to the spheroidal form in the ductile Ni-Resists. Copper interferes with the magnesium treatment and alloys high in copper cannot

Bronze is an alloy of copper to which tin, zinc and lead are added to achieve particular physical properties. Historically, it was the first metal used for casting. Brass is an alloy of copper and zinc. Both alloys have excellent machinability and corrosion resistance and are used for relatively small valves in low-pressure service. Valve Parts (Body, Bonnet, Trim) - ProjectmaterialsSep 20, 2017 · Which are the key parts of a valve? It is a complex mechanical device manufactured by assembling a number of different components:the body (the pressure containing shell, made of cast or forged steel, available with flanged, threaded or socket weld connection to pipes), the bonnet, the trim (the disc, the seat, the stem, and the other wet parts), the packing and, the actuator (manual, gear Valve Trim and Parts Including API Trim ChartsIt provides the passage for fluid flow. The body may be cast, forged, or fabricated. Sometimes valve bodies are manufactured by a combination of cast, forged, or fabricated parts. A variety of metals, alloys, and non-metals are used for the manufacturing of valve body. The valve body is also known as a shell.
BODY MATERIALS The control valve user normally specifies the body material, which is often the same material as the pipe. The most common choices of body material are carbon steel, chrome-molybdenum steel and stainless steel. Carbon steel is the most commonly used material for bodies.
