Product Details

Normally three pieces design Cast Steel Trunnion Ball Valves is for the bigger size than 12”,it have better price than Forged. . This series of valves are optional designed with double block and bleed or double piston type too . All stem and seats in valves are installed with sealant injection system to prevent leakage. It can be manual operated (lever or gearbox ), but also equipped with an actuator (electric, pneumatic, hydraulic, etc.).

Size of 3 Piece Internal Threaded Ball Valve:

A Ball valve is a quarter-turn rotary motion valve that uses a ball-shaped disk to stop or start the flow.

It resembles a plug valve in many ways. When a port in the ball is in line, it allows flow whereas when you

rotate the valve 90 degrees, solid part of the ball stop the flow.

Most ball valves are of the quick-acting type, which requires a 90° turn of the valve handle to operate the valve.

But in case large size valve which required considerable force to open or close the valve, the gear-operated

actuator is used. With this arrangement, a small handwheel is enough to operate a fairly large valve.

In this article, I have covered following types of Ball Valves that used in piping.

• Floating

• Trunnion Mounted

• 3 Way

• Top entry

• Side entry or split body

• Three-piece body

Applications of the Valve

• It can be used in different types of fluid services as an on-off stop valve that provides bubble-tight shutoff.

• It can be used in air, gaseous, and vapor services as well as hydrocarbon services.

• Metal seated valves can be used in high-pressure & temperature applications.

• it is widely used with instrument tubing to connect instruments.

• It is applied in food , bewerage, wine, pharmaceutical and chemical industries.

Advantages

• It is quick to open and close type that provides bubble-tight reliable sealing in high-pressure temperature applications.

• It is smaller and lighter than a gate valve of the same size and rating.

• Several designs of ball valves offer the flexibility of selection so that you can choose the valve that suits your requirements.

• Easy to operate and Cost-effective maintenance.

• The valve body can be replaced in any connections and the length will not change.
