Ua wili ʻia a hoʻopili maʻalahi ʻia ka puka kila kila maʻamau AISI304 a i ʻole 316 e like me ke aniani, hiki ke pale pono i ka hōʻino ʻana o ka hoʻopaʻa ʻana a me ka noho ma o ka wehe ʻana a i ʻole ka pani ʻana a hana i kahi sila nui aʻe. Ua mīkini ʻia ka lalo o ka lihi o ka puka i kahi bevel, i ʻoki ʻia ai i nā mea paʻa no kahi sila paʻa i ke kūlana pani. Hiki ke hoʻolako ʻia kahi pale pahi no ka pale hou aku i ka lepo.
Aia he 3 mau hiʻohiʻona e like me lalo:
1. Noho maʻamau NBR, EPDM, loaʻa pū kekahi ma PTFE, Viton, Silicone etc. Hoʻolālā kū hoʻokahi e laka mīkini i ke sila i loko o ke kino valve me ke apo paʻa kila kila. ʻO ka maʻamau he hoʻolālā sila unidirectional, a me ka sila bidirectional e like me ke noi.
2. He mau papa o ka ulana ʻana me kahi ʻōmole hoʻopaʻa maʻalahi e hōʻoiaʻiʻo ana i kahi sila paʻa. Loaʻa i nā ʻano mea like ʻole: Graphite, PTFE, PTFE + KEVLAR etc.
3. ʻO ka poloka alakaʻi ma ke kino valve e neʻe pono ai ka puka, a ʻo ka poloka extrusion e hōʻoiaʻiʻo i ka sila pono ʻana o ka puka.
Hoʻokō pono ʻo ZFA Valve i ke kūlana API598, hana mākou i nā hoʻāʻo kaomi ʻaoʻao ʻelua no nā valve āpau 100%, hōʻoia i ka hāʻawi ʻana i nā valves maikaʻi 100% i kā mākou mea kūʻai aku.
Hoʻohana ke kino valve i nā mea maʻamau GB, aia he 15 mau kaʻina hana mai ka hao a i ke kino valve.
ʻO ka nānā ʻana i ka maikaʻi mai ka hakahaka a i ka huahana i hoʻopau ʻia he 100% i hōʻoia ʻia.
