What Are You Looking For?
Built for harsh offshore and shipyard applications, this specialized valve casting provides a highly durable foundation for your fluid control assemblies. Poured from top-tier C954 and C958 aluminum bronze, the bare body naturally combats galvanic corrosion and chloride pitting, making it far superior to standard iron in brine and seawater environments.
To accelerate your factory production timeline, we deliver these lugged bodies fully processed. The side ears feature precisely tapped threads to support safe pipeline isolation, while the internal bore is CNC-machined to house soft seat liners perfectly. With a standardized top pad included, OEM brands can attach their own drive mechanisms immediately upon delivery without any secondary machining.

Tianjin,XingangLug Type Bronze Butterfly Valve Body C954 C958 C836
Engineered specifically for shipyard suppliers and marine valve assemblers, this bare bronze valve casting provides a heavy-duty foundation for saltwater fluid management.
Crafted from high-grade Aluminum Bronze (C954/C958) and Red Brass (C836), the body naturally resists bio-fouling, pitting, and galvanic corrosion. Supplied as a fully CNC-machined component, it features precision-tapped lug inserts that facilitate downstream pipeline maintenance. This allows OEM brands to immediately integrate their own PTFE or rubber seats, discs, and actuation hardware without secondary machining.

We supply these precision-machined bodies to global valve brands and assembly hubs. Once populated with soft parts, valves utilizing these bronze castings are primarily deployed in: Shipyard cooling circuits, offshore oil rig fire protection, reverse osmosis (RO) desalination plants, and coastal wastewater treatment facilities.
Q1: Why utilize C954/C958 Aluminum Bronze for marine assemblies?
A: Aluminum bronze provides superior tensile strength compared to standard bronze, while offering exceptional resistance to chloride-induced pitting and crevice corrosion. This ensures longevity for your final assembled product in marine environments.
Q2: Are the lug threads pre-tapped before delivery?
A: Yes, all threaded inserts on the lug body are precisely tapped at our facility according to your required standard (e.g., Metric, UNC), allowing your customers to perform safe dead-end service.
Q3: What seat materials are compatible with this machined bore?
A: The internal dimensions are machined to standard profiles, accommodating a wide variety of aftermarket and OEM seat linings, including PTFE, EPDM, and NBR, depending on your final media requirements.
