The body is the key element. It contains the moving components. They are in contact with the fluid. It has to withstand the pressure that exists in the piping system. The body is manufactured by forging or casting steel in many designs, shapes and material grades. In the oil industry the most common material for bodies is ASTM A105 for forged bodies.<\/p>\n\n\n\n

The trim is the collective name for the internal parts. It can be removed and they are replaced and are called wet. They are in direct contact with the conveyed fluid.  The trim includes components as the seat, stem, glands, disk, sleeves, and the bushings. It needed to guide the stem that made up the trim by the type of device. The factors to consider are temperature, pressure and type of fluid.<\/p>\n\n\n\n

The disc closes and opens or modulates the flow of the fluid. In the case of the gate valve and gate wedge is the disc of the valve. After the body and the bonnet, the disc is the third most important element for the good performance of the valve. Discs are manufactured of steel and they are mostly reinforced to enhance the properties of the base material.<\/p>\n\n\n\n

Valve material and its packing material is actually installed between the packing box and valve material which helps in preventing the outer leakage. There are many kinds of valve packaging materials such as flexible graphite pickings, vegetable fiber packing, PTFE valve packing, rubber filler, carbon fiber packing, metal and rubber valve packing and many more.<\/p>\n\n\n\n
