ʻO ka pahu pahu kihi keleawe hāmama lohi ʻo ia ka pāpaʻa huinakolu keleawe pāpaʻa hope kahe ʻana o ka ʻoki ʻoki ʻana i ka pahu wai.

ʻO ka maikaʻi o ka valve angle ma nā ʻano ʻehā:

1. Mea waiwai
ʻO ke kino nui, ʻo ke keleawe ʻulaʻula punching forging, hoʻohui pū ʻia, paʻakikī kiʻekiʻe, ʻaʻohe wai ʻōpala, hoʻoheheʻe keleawe, e hoʻopau i ka hana hoʻolei ʻana i ke one maʻamau e hoʻopuka i ka porosity a me ka wai leakage pilikia huna.

2. Hoʻolālā hale
Hoʻololi nā mea a pau i ka hana hāmama, hoʻolōʻihi i ka hoʻolālā ʻana i waho a me ka maikaʻi o ka hoʻokuʻu ʻana, ma o ka pahu hana hana hana kūikawā i lawe ʻia mai Iapana, hiki ke mālama i ke kiʻekiʻe o 90 ℃, haʻahaʻa haʻahaʻa embrittlement,;ʻO ke ʻano paʻa a me ka mānoanoa, mānoanoa & GT;1.8mm, me ke kiʻekiʻe kiʻekiʻe kiʻekiʻe pahū pahū-hōʻike hana, lohi wehe hoʻololi ke hoʻohālikelike ʻia me ka wikiwiki wehe ʻana, mālama i ka wai.

3. Electroplating papa
He ʻumi papa ʻāpana, lawa ka mānoanoa, ʻaʻahu, ʻoluʻolu, kala nani, nani

4. Lead standard
Ma ka laina me ka pae aupuni GB/T1176 i loaʻa i ke alakaʻi, ʻaʻohe pōʻino i ke olakino kanaka, e hōʻoia i ka hoʻohana ʻana o ʻoe a me kou ʻohana i nā huahana me ka ʻole o nā mea metala pōʻino, pale i ke olakino o nā mea hoʻohana.
