ONE-TWO-THREE PIECE BALL VALVE

ONE PIECE BALL VALVE

A one piece ball valve has a body and end connections formed from a single piece of material. This construction presents a comparatively reduced number of opportunities for leakage. The valve trim and seals are inserted through one of the end connections. This type of valve will not have a port size equal to the line size. The simplicity of the one piece body design tends to make their cost lower than the other versions. Once the valve is in place, it cannot be serviced without removing the entire valve assembly from the piping system.

Available in barstock or investment cast construction
2000WOG rating
Carbon Steel or CF8M Stainless bodies
Plated carbon steel or 316SS trim
¼” to 2” size range
API 607 5th Edition Fire-safe(OPTION)

TWO PIECE BALL VALVE

Two piece ball valves generally have one piece that includes an end connection and the body, plus a second piece that fits into the first that will hold the trim in place and provide the second end connection. The construction presents an additional leak potential where the two pieces are joined, but also allows disassembly of the valve for replacement of the internals. These valves can provide full port service and bidirectional flow shutoff.

Available in Brass, Bronze, Carbon Steel, Stainless Steel construction
Plated or 316SS trim
R-PTFE or TFM seats & seals
¼” to 4” size range
API 607 5th Edition Fire-safe(OPTION)

THREE PIECE BALL VALVE

A three piece ball valve essentially separates the connection portions of the valve assembly from the body of the valve. These will be more expensive than either of the other two types, but their allowance for removing the valve body and trim from the piping system while leaving the connections in place may prove valuable for many applications. Full port and bidirectional shutoff can be provided by this construction.
