Why Bronze Butterfly Valves Are Widely Used in Marine Applications
Bronze butterfly valves are widely used in marine and shipbuilding applications due to their excellent corrosion resistance, mechanical stability, and long service life in seawater environments. Excellent Corrosion Resistance in Seawater Marine piping systems are continuously exposed to seawater, salt spray, and humid conditions. Bronze alloys, especially aluminum bronze materials such as C95400, offer outstanding […]
Marine Bronze Butterfly Valve
Certified Reliability for Marine & Offshore Applications The Marine Bronze Butterfly Valve is specially engineered for shipboard and marine piping systems, where long-term reliability and corrosion resistance are essential. Manufactured from high-quality bronze or aluminum bronze alloys, this valve delivers excellent performance in seawater, salt spray, and harsh marine environments. With a compact structure and quick […]
U-Type Marine Concentric Butterfly Valve Introduction
1. Overview The U-type marine concentric butterfly valve is a wafer-style soft-seated valve designed for shipboard piping systems. Featuring a U-shaped body groove and a concentric disc-shaft structure, the valve provides reliable shut-off performance, excellent corrosion resistance, and easy installation with marine-standard flanges. It is widely used for seawater, cooling water, ballast water, fire-fighting, and […]
Introduction of SS304 Disc for Concentric Type Butterfly Valve
The SS304 disc is one of the most commonly used materials for concentric type butterfly valves, offering an excellent balance of corrosion resistance, strength, and cost-effectiveness. SS304 (AISI 304 / ASTM A351 CF8) is an austenitic stainless steel containing approximately 18% chromium and 8% nickel, which provides outstanding resistance to oxidation and a wide range of mild corrosive […]
Full Lined PTFE Butterfly Valve
What is a Full Lined PTFE Butterfly Valve? A full-lined PTFE butterfly valve is a butterfly valve whose wetted (fluid-contact) surfaces (body interior + disc / plate + sometimes stem bushing, etc.) are fully lined with PTFE (Polytetrafluoroethylene) or a similar chemically inert fluoropolymer. The lining protects the metal against corrosion and chemical attack. Useful […]
