J641H/Y pneumatic flange globe valve

J641H / Y Nā hiʻohiʻona huahana o ka pneumatic flange globe valve 1. ʻO ka huahana he hale kūpono, hoʻopaʻa hilinaʻi, hana maikaʻi loa a me ka helehelena nani; 2. ʻO ka ili hoʻopaʻa i uhi ʻia me ka co-based cemented carbide he maikaʻi ke ʻaʻahu kūʻokoʻa, pale ʻana i ka corrosion, abrasion a me ka lōʻihi o ka lawelawe ʻana; 3. He maikaʻi ke kūʻē corrosion a me ke kūʻē ʻana o ke kīpē ma hope o ka hoʻopiʻi ʻana a me ka hoʻomaʻamaʻa ʻana i ka nitriding; 4. Loaʻa i ka valve kahi hoʻonohonoho hoʻopaʻa hilinaʻi; 5.
