Pneumatic diaphragm control valve

i loko o ka punawai nui ʻole hiki ke hoʻololi i ka mea hoʻokele, kahi lima pale haʻahaʻa haʻahaʻa a me kahi pahu hoʻoponopono noho hoʻokahi me ka uhi ʻole o lalo.Hoʻonui ka mana kahe i ka 1/3.ʻO ke kikowaena haʻahaʻa o ka umekaumaha, ke kūpaʻa haʻalulu kiʻekiʻe a maʻalahi ke hoʻouka.ʻOi aku ka maikaʻi o nā papa kuhikuhi hana ma mua o nā huahana like.Hoʻohana nui ʻia nā huahana i nā ʻōnaehana hoʻomohala maʻalahi i nā ʻoihana me ka kemika, ka ʻaila, ka ʻoihana māmā, ka mana mana, a me ka metallurgy. E ho'āʻo mākou i ka mea maikaʻi loa e hāʻawi i ka valve control pneumatic kiʻekiʻe a me ka ʻenehana kiʻekiʻe no kāu papahana like ʻole no ka mana kahe. E nīnau iā mākou e kiʻi i ka hopena valve manuahi!

ʻO nā pōmaikaʻi o ka Pneumatic Control Valve:

COVNAPneumatic Control Valveskūpono no ka hoʻoponopono ʻana i ka kahe o nā paipu.Hoʻohana ʻia ka valve control pneumatic e ka ea compressed, me ka ʻole o ka uila, palekana a pahū.Loaʻa i ka mea hoʻonohonoho a hoʻopuka i ka hōʻailona hoʻomalu o ka ʻōnaehana hoʻokele automation ʻoihana e hoʻopau i ka hoʻoponopono ʻana o ke kahe a me ke kaomi o ka medium pipeline.Hoʻohana nui ʻia i ka hana moku, nā mea kanu mana, nā meaʻai a me nā mea inu, a pēlā aku.

Nā hiʻohiʻona o ZJH Series Pneumatic Diaphragm Control Valve:

●Hoʻokele ʻia ka valve Globe e ka mana pneumatic e hiki ke ʻae i kāu automation i maʻalahi a kōkua i kāu hoʻokele ʻana i ka medium me ka pololei.

●Loaʻa i ka ʻano noho hoʻokahi a me ke ʻano lima no kāu koho
