What is a 3-Piece Ball Valve?

The 3-piece ball valve is a type of valve that openly swings on both ends, which provides straightforward access to the inner valve.

This valve is preferred, especially when maintenance, cleaning, and repairing needs.

How Many Components Does a 3-Piece Ball Valve Have?

A 3-piece ball valve consists of a major component, namely:


  • Body. The dominant components in a 3-piece ball valve. It provides high quality, durability, and consistency due to its 100% stainless steel structure.
  • Two End Cap. It can connect to the pipe on the other side. It can be welded, flanged, or threaded.
  • Seat. It provides bubble-tight sealing to lessen friction,  operation torque, and wear off. 
  • Handle. This enables them to protect the position of the ball from involuntary movements.
  • Stem. These are self-adjusting which makes up for temperature changes. 
  • Stem Seals. It substantially raises the number of maintenance and adjustment cycles.
  • Double Lock Nut. It makes the handle safe and simply removed when the 3-piece ball valve is in full line pressure.
  • Stem Packing. It is adjustable that creates numerous seals within the body and stem of a  3-piece ball valve.

Why Use a 3-Piece Ball Valve?

Using a 3-piece valve provides a higher advantage than using other ball valves. It allows proper and uncomplicated services like assembly and disassembly without major cuttings. 

However, it can take different process conditions, pressures, flows, and temperatures. 

When is the Perfect Time to Use a 3-Piece Ball Valve?

A 3-piece ball valve is ideal, especially when the components in high-cycle and heavy-pressure encounter severe wear and tear.  

What are the Features of a 3-Piece Ball Valve?

The 3-piece ball valve offers dynamic performance, is cost-effective, is long-lasting to use, and is easy to repair. 

Aside from those features, the 3-piece ball valve is also composed of four significant features like fully encapsulated end screws, in-line repair, weld-in-place end caps, and a protected seat.

Fully Encapsulated End Screw

The 3-piece ball valve is constructed by putting screwed caps responsible for holding every end cap in place. It enables it to be protected from the outdoor environment since the screws are encapsulated.

In-line Repair

A 3-piece ball valve can mend without absolute removal from the line by removing three out of the four cap screws on the single side. 

Weld-in-place End Caps

A 3-piece ball valve also features a weld-in-place end cap with heat-dissipating rings. These end caps will allow the valve to weld in line without detaching the central body, saving materials and minimizing labor costs.

Protected Seat

It enables protection and isolates the seals and seats from the flow path that intercepts the cold flow. It also grants long-term performances, especially in demanding operations.

What are the Benefits of Using a 3-Piece Ball Valve?

A 3-piece ball valve is advantageous so that the structural ends of a ball valve can remain threaded in the pipe. 

Further benefits of a 3-piece ball valve include the following:

  • Easy to be maintained, disassemble and assemble
  • It is found more affordable to change seat seals rather than to change the entire valve
  • Does not have to remove the pipe connectors
  • Available in full port
  • It comes with plenty of available connectors like socket weld, FNPT, and tube socket weld.
  • It has long-term saving costs for extreme operation and high-cycle applications.

How Does a 3-Piece Ball Valve Construct?

A 3-piece ball valve is constructed by having a single central body and dual-pipe connectors. 

Those pipe connectors are generally welded and threaded into a pipe. It enables the main body to detach easily, especially during maintenance and repairs, even though the pipe connectors are not removed. 

On the other hand, the overall services of the valve will remain for its specific life duration while enjoying the low continuing maintenance expenses.

What are the Technical Specifications of a 3-Piece Ball Valve?

Some of the technical specifications of a 3-piece ball valve include the following:

  • Maximum pressure of 1000 PSI
  • Full port
  • Investment casting
  • Blow-up proof stem
  • Optional locking handle devices
  • Thread
  • Applicable temperature ranges are rated from -25° up to 365°.
