Nodweddion cynnyrch falf wirio swing safonol cenedlaethol
1. Mae gan y cynnyrch strwythur rhesymol, selio dibynadwy, perfformiad rhagorol ac ymddangosiad hardd;
2. Mae'r wyneb selio wedi'i orchuddio â carbid smentio Co yn seiliedig, sydd â gwrthiant gwisgo da, ymwrthedd cyrydiad, ymwrthedd crafu a bywyd gwasanaeth hir;
3. Mae strwythur siafft pin wedi'i adeiladu yn lleihau gollyngiadau allanol ac mae'n ddibynadwy wrth ei ddefnyddio;
4. Pan fydd y pwysau yn fwy na neu'n hafal i 16.0mpa, mabwysiadir y strwythur selio hunan dynhau yn siambr ganol y falf. Po uchaf yw'r pwysedd canolig, y gorau yw'r perfformiad selio;
5. Gellir dewis deunydd a maint y flange a diwedd weldio casgen yn rhesymol yn unol ag amodau gwaith gwirioneddol neu ofynion defnyddwyr i ddiwallu anghenion peirianneg amrywiol.
