Product Introduction:
JIS F7301 bronze straight globe valve is manufactured per JIS F7301 marine standard, with full CAC406 tin bronze valve body. Rising stem design shows opening status clearly for ship inspection. Flanged connection delivers excellent anti-vibration performance for marine vessels.Bronze hard sealing realizes tight shut-off and precise flow throttling. Outstanding seawater anti-corrosion capability resists salt spray and marine organism adhesion, widely used for ship cooling water, fire water, ballast water, steam and fuel oil pipeline.We can supply CCS, NK marine class certificate for ship newbuilding and repair projects. High pressure version JIS F7303 (16K) is available for steam & high-pressure oil pipeline.
Advantages:
Full bronze body, superior seawater corrosion resistance.
Rising stem for visible valve opening indication.
Straight flanged connection for straight pipeline installation.
Bronze hard seal for shutoff & throttling dual purpose.
Marine certified (CCS/NK) for ship engineering.
Easy on-site maintenance for packing & trim parts.
