Khatello e tloaelehileng ea phepelo ea Jeremane hangata ke PN10 ho PN320, ho sebelisoa maemo a DIN; Ha belofo e flanged, sebelisa e lekanang flange tekanyetso. Litekanyetso tsa mantlha tsa belofo ke maemo a Amerika a standard petroleum Association API standard, American standard ANSI, standard standard DIN, standard standard ea JIS, GB, standard standard ea Europe EN, standard standard BS.
Ka mantsoe a mang, li-valve tse tloaelehileng tsa Amerika li entsoe, tsa etsoa, tsa hlahisoa le ho lekoa ho latela maemo a Amerika. Li-valve tse tloaelehileng tsa Jeremane li entsoe, tsa etsoa, tsa hlahisoa le ho lekoa ho latela maemo a Jeremane. Sephahla se tloaelehileng sa naha ke, ho latela moralo o tloaelehileng oa China, tlhahiso, tlhahiso, phumano ea li-valve.
