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.

Butterfly Valves

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

  • Uses of Butterfly valves:
    Butterfly valves are considered to be the most economical and reliable type of pipe valves. Technological innovations combined with the simple design of the butterfly valve has made it a dependable, economical and flexible solution to a variety of industrial flow control needs. These valves have many advantages over other valves like gate, globe, plug, and ball valves, especially in large valve applications. The most obvious advantages are savings in weight, space, and cost. The maintenance cost is low because there are a less number of moving parts and there are no pockets to trap fluids. They are widely used in water distribution and waste water processing.

Tripe Eccentric Butterfly Valve :

Butterfly Valves

Sleeve Type Soft Sealing Plug Valve Acc.To ANSI :

Butterfly Valves

Main structural features:

Bolt cover,plug 90 degree around.
Its sealing is realized by the sealing face around the sleeve.It has unique 360 degree metal edge for protection and fixing of the sleeve.There is no cavity in the valve for accumulation of medium.Metal edge provides the function of self-cleaning when the plug is rotated,applicable to the operation condition thatis glutinous and apt to smudge.Double direction.
