The material of ZECO gate valve includes, but is not limited to stainless steel, carbon steel, forged and cryogenic.  Water, oil, natural gas, steam, and other non-corrosive media the most commonly used material of valve body, valve bonnet, and the wedge is A216 WCB, and after NACE MR-01-75 or NACE MR-01-03 treatment, A216 WCB material is also often used in the condition of slight corrosion. One thing to note, however, is that the temperature range of A216 WCB is\u00a0-29\u2103 to 425\u2103.  Gate Valve Parts  The valve body is the primary part of the valve which holds everything together. Mostly it is connected to piping through flange and gasket. It is the pressure boundary of the valve. The valve bonnet is the second boundary of pressure. It is connected with a valve body with bolts or flange. The valve trim collectively stems, seat, and the disk is known as valve trim. Valve performance is dependent on seat and disk arrangement. The seat and disk are the most important part of the gate valve. It contains a gate-type disk and seat which fits the disk tightly. The stem connects the actuator and disk in the gate valve. It opens and closes the disk and seat arrangement. Two types of the stem are available one is rising which rises when we open the valve and the other is non-rising which has no vertical motion. Valve Actuator is a manual wheel which operates stem and disk arrangement.  How to Select Valve Materials  The challenge in making a material choice is actually verifying that the chosen material best fits the application. This involves taking into account working conditions and flow media properties.  Most important concerning the working conditions is to know the pressure and temperature ratings and for working media is to take in consideration corrosive and erosive properties. Additionally, it might be needed to consider thermal and physical shock, line stress and fire hazards.  Broadly speaking when considering temperature limitations of different groups of materials Table 1. should be used as general reference for material selection.   Range Temperature(\u00b0F) Material  Very High 2000 Refractory Metals, Ceramics  High 1600 High Temperature  1200 Alloy Steels  Intermediate 1000 Carbon Steel  650 Ductile Iron  550 Bronze  450 Cast Iron  150 PVC Plastic  Low -250 Low Alloy Steels  Bronze  Very Low(Cryogenic) -450 Bronze, Austenitic Ductile Iron  Austenitic Stainless Steels   In some cases a compromise must be reached in selecting a material. Some service conditions require use of exotic alloys and metals to withstand particular corrosive properties of the flowing fluid. These materials are much more expensive than common metals, so economy may also be a factor in material selection. Table 2 shows ASTM materials widely used for valve bodies and bonnets.    ANSI Class Material ASTM Specification  125 Bronze B 62  125 Cast Iron A216 Cl. B  150 Bronze B 62 \/ B 148  150 Carbon Steel A216 GR.

WCB  600 Forged Steel A105  Table 2  The trim typically includes a disk, seat, stem, and sleeves needed to guide the stem. Valve trim materials in relation to temperature limits should be selected in according to Table 3.

A352 LCB, A352 LCC is usually used for a low-temperature application, usually, the medium is of low-temperature but over -46\u2103 or through conduit gate valve is installed outdoor in area of a cold environment. But these materials can not be used for high-temperature over 345\u2103.  A351 CF8, A351 CF8M, A351 CF3, A351 CF3M, these austenitic stainless steel are anti-rust and anti-corrosion, suitable for the medium of various kinds of acid. A351 CF8, A351 CF8M, A351 CF3 &amp; A351 CF3M can be used in most low temperature conditions, but it needs cryogenic treatment. It can also be used in most high-temperature conditions, but there are corresponding standards for carbon content.  Aluminum-bronze like B148 C95800, B62 C83600, B283 C61300, and other Al-bronze are perfectly suitable for seawater application.
