About the HALVORN BV25
BV25 is a two-piece threaded ball valve: a cast stainless body and a threaded end piece clamp a floating ball between two PTFE seats. The 25 mm bore matches the pipe, so an open valve adds almost no restriction and the line can be pigged or cleaned straight through.
The stem goes in from inside the body and bears up against the neck on a thrust washer, so line pressure can never blow it out. A gland nut above the PTFE packing can be re-tightened in service, and a stop washer keyed to the stem meets a cast lug at open and at shut.
HALVORN is a fictional brand made for this Proofscene demonstration. The model is drawn as CAD, part by part; the figures below are illustrative values typical of this valve class, not a datasheet.

Fictional demonstration product. HALVORN is not a real company and BV25 is not a real part: the geometry is drawn by Proofscene from published DN25 two-piece valve proportions, and every figure on this page is illustrative.
