  1. WORKING OF FLOATING BALL VALVES

  2. INTRODUCTION • Floating ball valve uses a ball as the formation to prevent the flow of liquid and to shut the cross-section of the pipe. The main characteristic of a floating ball valve is, the ball has no definite structure to support it and it remains dangled in the fluid while the valve seats are static. • There are different standards available in floating ball valves some are, Design standard API 608, Test standard API 598, Fire Standard API 607, etc.

  3. CATEGORIZATION Floating ball valve is categorized by, One-piece floating ball valve Two-piece floating ball valve Three-piece floating ball valve

  4. ONE-PIECE FLOATING BALL VALVE: • One-piece floating ball valve and flange gate valve are the same type of valvebut the difference exists in the closing part only. A sphere is used in one piece ball valve facilitating its rotation around the centerline of the body. • The ball valve is mainly used to shut off, dispense and change the direction of the medium in the pipeline.

  5. TWO-PIECE FLOATING BALL VALVE: • Two-piece floating ball valve has two parts one is on the left and another is on the right, these two parts are connected by threads and bolts. • This type of valve can withstand both high temperature and high-pressure conditions.

  6. THREE-PIECE FLOATING BALL VALVE: • In three-piece floating ball valve, the body is composed of three segments from left to right, one is the main body and the other two segments are bonnets; the ends are connected through threads and bolts like two-piece floating ball valve.

  7. WORKING OF FLOATING BALL VALVE • Floating ball valve has the ball inside the valve that is kept in the particular position by compressing two elastomeric supports towards the ball so that the ball can float inside the valve. • At the top of the ball, the shaft is connected and allows the switch from open to closed position with a quarter-turn movement. When the shaft is moved, a load is applied to the ball which gets pressed against its seats.The ball floats and the seats are stable

  8. ADVANTAGES • Floating ball valve is simple in design, small in size and weigh less, • Plastic is used for sealing purposes, which has a good sealing performance and is safe to use, • It is easy to operate, fully open and closed position, at ease by remote control. • Valvualsfevisa being theball valve supplierdeliver reliable products, and they are known for being the best valve suppliers all over.

  9. DISADVANTAGES • The sealing surface may suffer damage when roughly used, • If the medium contains particles, then it is not suitable for those applications, • Heavy sealing is needed for hard sealed valves.

  10. CONCLUSION • We, Fevisa being one of the leading Valve Manufacturers, ball valve suppliers, gate valve supplier, and more. Our valves made in Europe with strict adherence to the International Standards like WRAS approved valves and UL FM approved valves. • We are popularly known as valves suppliers and valve stockiest in Dubaiand the team of experts at fevisa ready to help you out with the best choice of Ex-stock valves.
