He kūpono ka ?a?ahu ho?opa?a valve no nā ?oihana he nui, eia kekahi o nā wahi nui o ka noi:

Ka mālama ?ana i ka ikehu a me ka ho?emi ?ana i ka ho?ohana ?ana
No nā pipelines a me nā lako hana ma ke kahua ?oihana, e like me nā pipelines mahu, nā reactors, a me nā mea ?ē a?e, hiki i ka ?a?ahu insulation thermal ke hō?emi i ka pohō wela i ke kaiapuni a puni, e mālama i ka medium kūloko i ka mahana e pono ai.

Ke nānā ?ana i nā loli o ka mahana o waho ma mua a ma hope o ka ho?ololi ?ana
E koho i kekahi mau wahi nānā no ka ho?ololi ?ana i ka insulation wela e mālama ai i ka ikehu o nā lako wela a me nā paipu, a e ana i ka mahana o waho o nā wahi nānā ma mua a ma hope o ka ho?ololi ?ana.
