A butterfly valve is a rotary motion valve. The main purpose of butterfly valve is used to stop, regulate, and start fluid flow. This type of valve is easily and quickly operated because there is a 90 degree rotation of the handle which moves the disk from a fully closed to fully opened position. Butterfly valves are available in various sizes and materials. Infact, the larger sized butterfly valves are actuated by hand wheels which are connected to the stem through gears and they provide mechanical advantage at the expense of speed. Parts of a butterfly valve: The butterfly valve consists of only five main components. They are as follows: Body: These valves have bodies that fit between two pipe flanges. Disc: The disk is the flow closure member of a butterfly valve. Stem: The stem of the butterfly valve is either a one-piece shaft or a two-piece, also known as split-stem design. Seat: The seat of a butterfly valve utilizes an interference fit between the disk edge and the seat to close or to shutoff. SOperator Type of Valves: A valve is a piping components complete with operating system, able to control or shut off a fluid flow Valves are divided in: Ball Valve, Butterfly Valve, Check Valve, Gate valve, Globe Valve, Plug Valve, Power Station Valves, Y-Type Strainer, New Products ?© PipeFitting.Asia | E-mail: pfAsia8@gmail.com |
