Butterfly Valve Manufacturer

Backed with the rich industrial experience, we are leading Butterfly Valve Manufactures in India. A Butterfly valve is a quarter-turn rotational motion valve that is used to stop, regulate, and start flow.

The offered Butterfly valves are easy and fast to open. A 90° rotation of the handle provides a complete closure or opening of the valve. Large Butterfly valves are usually equipped with a so-called gearbox, where the hand wheel by gears is connected to the stem. This simplifies the operation of the valve, but at the expense of speed.

We are providing Butterfly valves which have a short circular body, a round disc, metal-to-metal or soft seats, top and bottom shaft bearings, and a stuffing box. The construction of a Butterfly valve body varies. Butterfly valves are even available with flanged, threaded and butt welding ends, but they are not often applied.

Typical applications of Butterfly valves

The following are some typical applications of Butterfly valves:

  • Cooling water, air, gases, fire protection etc.
  • Slurry and similar services
  • Vacuum service
  • High-pressure and high-temperature water and steam services

Advantages of Butterfly valves

  • Compact design requires considerably less space, compared to other valves
  • Light in weight
  • Quick operation requires less time to open or close
  • Available in very large sizes
  • Low-pressure drop and high-pressure recovery

Disadvantages of Butterfly valves
  • Throttling service is limited to low differential pressure
  • Cavitations and choked flow are two potential concerns
  • Disc movement is unguided and affected by flow turbulence
