Ball valve used to control fluid, not only controll the area which fluid pass, also have low pressure drop. Ball valve used to control and regulate fluid, not only control the area which fluid pass, also have low pressure drop. Ball valve has the advantages like simple structure, good sealing, small size, light weight, small installation size, low turning torque and easy operation; these makes ball valve easy to achieve the role of fast opening and closing. Ball valves are also suitable for use in piping systems with light construction, low pressure cut-off (small pressure difference) and corrosive media; mainly used in the pipeline is to cut, distribute and change the flow direction of the medium. The range of TVCCL ball valves is available in a wide range of options, sizes and materials.
A wafer-style butterfly valve is the most economical version and it is sandwiched between two pipe flanges. Easy installation, many connection options. Butterfly valves are used for on-off or modulating services and are popular due to their light weight, small installation footprint, lower costs, quick operation and availability in very large sizes. These valves can be operated by handles, gears or automatic actuators.
Butterfly valves possess many advantages over gate, globe, plug, and ball valves, especially for large valve applications. Savings in weight, space, and cost are the most obvious advantages. The maintenance costs are usually low Butterfly valves are especially well-suited for the handling of large flows of liquids or gases at relatively low pressures and for the handling of slurries or liquids with large amounts of suspended solids.
There are several types of end connections that allow for easy installation of these valves, but the most common are lug and wafer style, both fitting between flanges. Lug style butterfly valves are similar to 3-piece ball valves -they allow adjacent piping to be removed independently. This is achieved by using two different set of bolts, with each attaching the pipe flanges at either end of the valve body. With this connection to the valve, the ends of the pipe sections can be removed and replaced independently. Installation is also fool-proof as the number of lugs make centering the valves easy.
A ball valve is known for its durability, simplicity, and excellent sealing properties. They provide excellent shutoff even after years of service. This makes a ball valve an excellent choice as a shut off valve. They also provide better resistance to contaminated media than other valves. Ball valves are not commonly used as control valves due to its less precise flow control. However, they are cost effective and can be used in applications that do not require precise flow control accuracy.
PFA Lined Ball valves are commonly used in pulp and paper operations, Chlorine water, chlorine dioxide, sodium hypochlorite and sulphuric services. Ball valves are primarily used to shut off or turn on the media, as well as to regulate and control fluids. The ball valve's cut-off function is achieved by the ball being pressed against the valve seat under the action of the medium. The ball valve can be closed by rotating 90 degrees and it can stop the medium with a small rotating torque. Due to its versatility, ball valves are widely used in the chemical industry, petrochemical and other related industries. Our ball valves series with a wide range of options, sizes and materials, we offer flanged or threaded ends. For example, we offer bodies in bronze-ALBC3 (ASME B148 C95800) for seawater applications in demanding conditions. Some of our ball valves offer a fire safety (API 607) design. Valves for higher pressure ratings and temperatures are available upon request.
