Nodweddion Dylunio Cynhyrchion
Falf giât yw un o'r falfiau torri a ddefnyddir amlaf, * fe'i defnyddir yn bennaf i gysylltu a datgysylltu cyfryngau yn y bibell. Mae'r ystod o bwysau, tymheredd a chalibr addas yn eang iawn. Fe'i defnyddir yn helaeth mewn cyflenwad dŵr a draenio, nwy, pŵer trydan, petrolewm, diwydiant cemegol, meteleg a phiblinell ddiwydiannol arall, sef cyfryngau sy'n stêm, dŵr, olew i dorri neu addasu llif y cyfryngau.
Prif Nodweddion Strwythurol
Mae ymwrthedd hylif yn fach.
Mae'n fwy arbed llafur wrth agor a dosio.
Mae'r cyfeiriad llif yn gyffredinol anghyfyngedig, Hawdd i'w osod.
Strwythur rhesymegol, selio dibynadwy, perfformiad rhagorol, ymddangosiad pert.
