O va'a siaki tisiketi fa'alua o va'a siaki su'ega tasi-tisiki fa'atasi ma feso'ota'iga lua. O va'a siaki uma e sili ona manifinifi e puipuia ai le fete'ena'i i le paipa. O va'a siaki siaki fa'alua o le H74X ma le H74H o lo'o i ai le lelei o le fausaga faigofie, foliga matagofie, mama mama ma fa'apipi'i faigofie. E sili ona talafeagai mo le tuʻuina atu o le vai, suauu, vailaʻau, metallurgical ma isi vaega tau alamanuia. E sili ona fetaui mo nofoaga e faʻatapulaʻaina avanoa faʻapipiʻi. H74 fa'asologa lua-kilipi tisiketi siaki valve ua mamanuina ma le lua-kilipi sootaga, e ala i le tasi-tisiki swing ituaiga valves otometi, ma uamea stainless po o Stelli surfacing e mafai ona faaaoga mo le faamaufaailoga o le tino valve ma tisiki.
