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. It handles most non-corrosive liquids and gasesChemical resistance of materials TamesonValve body materials. The most common body materials for the valve body are brass, stainless steel and nylon. Brass is the most popular material for solenoid valves. It is very robust and resistant to many chemicals, but for example less suitable for sea water or distilled water. Stainless steel is recommended for corrosive media, such as seawater.
Jun 11, 2016 · For example, if the flow media contains glycol for fire resistance, the body, seals, and packing components that make up the valve must be specified with an understanding of the possible effects that glycol may have on those valve components (see Figure 2).

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.
Sep 04, 2016 · The guiding document for control valve body selection is the Piping Material Specification(PMS). From the PMS, one can pick the valve body material for the particular piping class corresponding to the service in which the valve is installed. If the PMS specifies WCB as the body material, WCC can also be selected instead, as WCC is considered superior to WCB.MAJOR VALVE BODY MATERIALS, COMPOSITIONS & Global Supply Line can supply valves in the following body materials Carbon Steel Low Temperature Carbon Steel Low Alloys 13%Cr Stainless Steel Austenitic Stainless Steel Precipitation Hardening Stainless Steel Duplex & Super Duplex Stainless Steel Bronze Ni Alloys (825, 625, 718) TitaniumTECHNICAL INFORMATION Valve Body Materials Valve Body Materials. The table below is a metric for the selection range based on temperature. Since in reality the pressure can have a major effect, when selecting materials, please refer to the JIS and ASME JPI temperature pressure stage tables.
If you walk through any large PVF warehouse and look around, it seems that valves come in three flavors black, silver and gold. These flavors are really iron, steel and bronze, which constitute the lions share of valve body materials used in todays valve industry.The A to Z of Valve MaterialsThe answer is that valve materials, particularly valve body materials, are chosen primarily for two reasonsstrength and corrosion resistance. And in valve material selection, one type does not fit all. Withstanding Stresses.Titanium alloy valve body material - Red Point Alloys BVLarge variety materials. The valve body material can be offered in special materials and standard materials. Next to stainless and carbon steel, we manufacture valves in special materials such as titanium, nickel alloys, HASTELLOY®*, INCOLOY®, MONEL®, Alloy 20, super-duplex, corrosion resistant alloys and urea grade materials.
Sep 20, 2017 · MATERIALS FOR BUTTERFLY VALVES VALVE BODY. Butterfly valves, like any other type of valve, are available in multiple materials and combinations of materials (body, disc, seat). The selection of the materials is based on the fluid to be shut off, the pressure and the temperature of the application at hand.VALVE TRIM MATERIALS, API 600 TRIM CHART API Trim VALVE TRIM MATERIALS The trim of a valve is the set of replaceable parts of a valve. The trim shall be selected carefully, depending on process parameters as fluid, working temperature pressure and valve type. The API 600 norm defined standard numbers to indentify the trim in terms of combinations of materials for the replaceable parts of the valve body materialsValco Valves - Materials of ConstructionThe standard valve body material is Nitronic 60, a gall-resistant stainless steel which has proven superior to Type 316 or 303 in the majority of applications. Valves may also be ordered in Hastelloy C-22, Inconel 600, Type 316 stainless, Monel 400, Nickel 200, Nitronic 50, or Titanium.

The key specifications for cast steel valves body materials are ASTM A216 (WCA, WCB, WCC), ASTM A352 LCB LCC (low-temperature), and ASTM A351 CF8 CF8M. ASTM A105, A350 and A182 cover body materials for small size (or high pressure) forged valves.Valve Materials - an overview ScienceDirect TopicsMost control valve materials can be placed in two categories The pressure containment materials for valve body, bonnet, bottom flange, and bolting. The valve trim materials for valve plug, seat ring, cage, valve stem, guide bushing, and packing box parts. For oxygen services, body and trim materials shall be AISI-316 stainless steel.
Brass is an alloy of copper and zinc. It has excellent forgeability and machinability and is more economical than bronze. Cast iron lining. Nylon 11 and epoxy resin are powder-coated on the inner and outer surfaces of an iron valve, creating a lining that is useful for preventing red, rusty water.Valve Stem Material Selection for Offshore Actuated ValvesSep 11, 2020 · Valve trim materials are pressure-containing parts which should have the material quality minimum to the body of the valve. The main trim components, which are also called wetted parts, are closure member, seat and stem. The stem of the valve should have sufficient mechanical strength to withstand the loads implemented from the operator.Valve Trim and Parts Including API Trim ChartsA valve body has different types of passages through which fluid passes. Design of these passages depends on the function of a valve. The first body type is Reduced bore, in this type, passage diameter of the valve is smaller than the connecting This is the most common design as it will reduce overall valve cost at the same time it narrows the fluid flow.
The valve body may be produced with one material and the trim, may or may not be made of the same material. Valve trim is exposed to flow media and may be made of a different material than the valve body. The trim is normally more corrosion resistant than the valve body, so that corrosion is less likely to occur at the valve seating area.
