About – BUTTERFLY valves

The control application in pumping systems has led to the development of control valves, such as Butterfly Valves. Sunshine Metal Industries’ Butterfly Valve has surpassed the Gate Valve, Ball Valve, and Globe Valve in many application areas. The gas-tight sealing, excellent control characteristics, and directional flow have earned Sunshine Metal Industries’ valves recognition from various industries. The centrally mounted disc, shafts, and bearings have minimized head loss. Its low weight and compact design have made it widely accepted in industries such as Chemicals and Petrochemicals, Water Treatment, Agriculture, and many others.

A Ball Valve is a type of quarter-turn valve that utilizes a hollow, perforated, and pivoting ball to control the flow through it. The valve is open when the ball’s hole aligns with the flow and closed when it is pivoted 90 degrees by the valve handle. The handle lies flat in alignment with the flow when open and is perpendicular to it when closed, providing easy visual confirmation of the valve’s status.

Ball Valves are known for their durability, performing reliably even after many cycles, and closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, often preferred over Gate and Globe Valves. However, they do not provide the fine control required for throttling applications.

  • Compact construction: Results in low weight and requires less space for storage and installation.
  • Central shaft position: Provides 100% bidirectional bubble-tight shutoff, making installation acceptable in any direction.
  • Full bore body: Ensures low resistance to flow.
  • No cavities in the flow passage: Facilitates easy cleaning and disinfection, suitable for potable water systems.
  • Liner: Creates a seal with mating flanges, preventing media contact with the valve body.
  • Low operating torques: Leads to easy operation and economical actuator sizing.
  • PTFE lined bearing on shaft: Allows for low friction and wear without the need for lubricants.
  • Seldom maintenance: Contributes to a long service life.
  • Low driving moment: Ensures easy and quick operation.
