What is HF valve seat?
HF valves conform UOP (Conocophillips) It is used to convert isobutane and low-molecular-weight alkenes (primarily a mixture of propene and butene) into alkylate, a high octane gasoline component. This process occurs in the presence of a strong acting acid such as sulfuric acid or hydrofluoric acid (HF) as catalyst.
What is WCB in gate valve?
WCB(CARBON STEEL) Gate Valve.
What is trim in gate valves?
The operating parts of a valve which are normally exposed to the process fluid are referred to as ‘valve trim’. Usually parts like stem, plug, disc, seating surface etc. are called as valve trim. Valve trim is the physical shape of the plug and seat arrangement.
What is trim in butterfly valve?
The internal parts of the valve body, stem, seating material, package, disc, plug, back rings, etc., are collectively referred to as the trim.
What is one type of valve hardfacing?
Internal parts of many different types of valves may benefit from hardfacing, such as gate, globe, check and butterfly valves.
Are valves considered fittings?
A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category.
What is WCC valve?
WCC stands for “Wrought Carbon” with Grade C. Sometimes you can think first letter “C” as casting. There are 3 kind of Grade A, B & C which define the ductility & tensile strength. Grade WCC is having very good yield strength as compare to Grade WCA and Grade WCB.
What is the seat of a valve?

What is bonnet in valve?
An assembly including the part through which a valve plug stem moves and a means for sealing against leakage along the stem. It usually provides a means for mounting the actuator. Sealing against leakage may be accomplished by packing or a bellows.
What is hardfacing in valves?
Hardfacing is a metalworking process where harder material is applied to vulnerable surfaces to mitigate such damage. Whole components could be made from the hard materials, but that generally is a much more expensive solution.
What is Hardfaced valve trim?
Hardfacing (a standard term for a wear-resistant weld overlay) is commonly used for seat and guide surfaces on valve trim of all styles.
