3-Piece Ball Valves


3pc ball valves offer in-line maintenance possibility, where combination of end connections offer great flexibility.

Three-piece ball valvescomposed of 3 separate pieces。it is preferred wherever regular cleaning or repair is required.

As the name implies, a two-piece ball valve consists of two pieces, one with an end connection and the body.

The ball valve ends can remain flange/threaded/weld connection into the pipe, while the center section can be removed.

The valve with butt welding end connection ensures no accidental leakage.

Unlike butt weld fittings, socket weld fittings are mainly used for small pipe diameters.

In general, soft seats are made of thermoplastic materials such as PTFE. metal seats incorporate a metal-to-metal seal between the seats and ball of the valve assembly.

Soft seats are not recommended for dirty or abrasive process fluids.

Soft seats can break under these conditions, causing leaks in the valve.

In general practice, metal seats can stand up to extreme flashing, hydraulic shock, abrasive process fluid, and high temperatures.

They are also ideal for high erosion or corrosion applications
