GB/T 587 Bronze Marine Globe Valve | Corrosion Resistant
A premium bronze valve designed specifically for seawater and corrosive environments. It features an aluminum bronze stem and reliable sealing components. Ideal for sea water lines, fresh water, and fuel systems up to 250°C.
Accreditation and Certificates:
The GB/T 587 Marine Globe Valve addresses the challenge of salt corrosion. The body is cast from high-quality bronze. The stem utilizes aluminum bronze for added strength and resistance. This material combination makes it the standard choice for seawater piping systems.
Beyond seawater, it handles fresh water, oil, and steam effectively. The non-metallic sealing materials are selected to withstand temperatures up to 250°C. Whether you need a straight (Type A) or angle (Type B) flow path, this valve delivers long service life with minimal maintenance.
