China Bronze Disc Lug Butterfly Valve Factory & Manufacturer

Precision starts at the melt. We are the specialized manufacturer that controls the entire process of your bronze disc valves, from our own foundry to final assembly.

Our lug-style Butterfly Valves feature a disc cast from high-grade bronze (C95400/C95500/C95800) in our foundry, ensuring superior corrosion resistance for seawater, potable water, and industrial fluid service. The robust lug body provides a secure, bolt-through flange connection for reliable isolation.

Our Integrated Manufacturing Process:
• Alloy & Casting: We melt and pour certified bronze alloys in-house for full traceability.
• Precision Machining: CNC-machined disc and stem surfaces ensure a perfect seal with the resilient liner.
• Standard Build: Ductile iron lug body with epoxy coating; bronze disc; EPDM seat (standard).
• Key Specs: DN50 to DN300, PN10/16 pressure rating. Lever, gearbox, or factory-fitted actuation.
• Quality Assurance: Each valve undergoes hydrostatic shell and seat testing before leaving our factory.

As the manufacturer, we provide OEMs and distributors with consistent quality, complete customization, and direct technical support. Whether you need standard valves from stock or a modified design, we build it.
