In 2021 Penta developed a new 3 pieces ball valve for temperature up to +400°C
Penta is pleased to announce the development of a new series of metal-seated ball valves with typical 3-pieces construction.
The new model, called 3PZ, will be suitable for temperatures up to 400°C and pressure classes up to ANSI 600. As with any other 3-pieces ball valve, it will be possible to dismount the central part of the body without dismounting the pipe connections in order to make a maintenance but, differently than any other 3-pieces ball valve, the central part of the body can be pressure tested before reassembling it on the piping system to verify the seat and stem tightness.
The new series will be available with Pentafite metal seats, Stellite, Chrome Carbide, Tungsten Carbide hard faced ball and seats, as well as standard Peek, RPTFE and TFM soft seats.
It will be possible to add a 100mm stem elongation to move the operator away from overheated body and increase safety against fugitive emissions. The new model is subjected to international patent.
