He aha ka resilient seated gate valve (RSGV)?

ʻO ka pahu puka puka noho kūpaʻa (RSGV),he kumumanaʻo hoʻolālā i mana nui i ka makemake no ka hoʻohana ʻana i nā ʻōnaehana hoʻolaha.

ʻO kapaʻa paʻa noho ʻīpuka valveloaʻa i kahi wili i hoʻopili piha ʻia me ka lāʻau EPDM i hoʻopaʻa mau ʻia i ka wedge a kū i ka ASTM D249.Hoʻopili ʻia ke kino valve, ka pāpale, a me ka pā palaka me ka fusion bonded epoxy (FBE), nani ke nānā aku a me ka pale maikaʻi loa.Hoʻokomo pū ʻia nā hoʻonohonoho koho i kahi Non-Rising Stem (NRS) a i ʻole Outside Screw & Yoke (OS&Y).Kiwi puka puka kūpaʻaHiki ke hoʻohana ʻia me kahi Spur a i ʻole Bevel Gear, a me ka mea hana uila.

nā ʻīpuka noho kūpaʻakaulana loa ia no ka hana ʻoihana.

ʻO nā hiʻohiʻona nui o NORTECH resilient seated gate valve (RSGV)?

ʻO ke kino hana ʻia me ka hao ductile e ka hoʻoheheʻe pololei ʻana,Ua hoʻolālā ʻia e ka polokalamu 3D, me ka hoʻopaʻa ʻana i nā mea i hoʻopau ʻia no ka hale.
