Gelwir y falf wirio hefyd yn falf llif cownter, falf wirio, falf pwysedd cefn a falf unffordd.Mae'r math hwn o falf yn cael ei agor a'i gau yn awtomatig gan yr heddlu a gynhyrchir gan lif y cyfrwng piblinell ei hun.Mae'n perthyn i falf awtomatig.Defnyddir y falf wirio yn y system biblinell.Ei brif swyddogaeth yw atal ôl-lif cyfrwng, cylchdroi cefn y pwmp a'i fodur gyrru, a rhyddhau cyfrwng yn y cynhwysydd.Gellir defnyddio'r falf wirio ar y biblinell hefyd i gyflenwi'r system ategol lle gall y pwysau godi uwchlaw pwysau'r brif system.
Gellir gosod y falf wirio ar biblinellau gyda chyfryngau amrywiol yn ôl gwahanol ddefnyddiau.
