Product Detail

The 3 piece ball valve has two body joints which means the body is made out of three pieces, giving rise to the name “three-piece. This 3 piece body design allows a larger ball to be installed at the time of manufacture, making this a full bore ball valve (Full port). Full port means that the bore has the same inside diameter as the piping.

3-Piece Ball Valves is a quarter-turn valve that uses a hollow, perforated and pivoting ball to control flow through it.  It is open when the ball’s hole is in line with the flow. It 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, making for easy visual confirmation of the valve’s status.


A three-piece ball valve is preferred wherever regular cleaning is required. The valve body is composed of 3 separate pieces held together by bolts, which can be easily removed for cleaning and servicing. A unique advantage of the 3 piece valve design is that the ball valve ends can remain threaded into the pipe, while the center section containing the ball can be removed. These 3 piece ball valves have been specifically designed to be easily disassembled, cleaned, and reassembled.

Their best feature is that they are the easiest ball valve to clean and service and this can be done without removing the threaded ends from the pipe.

Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse.   These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack their fine control in throttling applications.


3 piece stainless steel ball valves also called 3 SS ball valves, are widely used for a variety of sanitary applications that are required for pharmaceutical and food/beverage industries.
