Custom Lug Butterfly Valve for Seawater - Leading Supplier & Manufacturer
When it comes to reliable performance in marine environments, our Lug Butterfly Valve for Seawater is your go-to solution. We understand the specific demands of seawater applications, and that’s why this valve is designed to withstand corrosion while ensuring optimal flow control. As a manufacturer, we offer customization options to meet your unique specifications, ensuring that you receive a product that perfectly fits your needs.
When the pipeline carries seawater, reliability is not just a feature—it’s a requirement. Engineered for the harsh, corrosive marine environment, this lug-style butterfly valve is manufactured to provide lasting performance and secure isolation in seawater cooling, firefighting, ballast, and intake systems.
We build this valve using corrosion-resistant materials selected for long-term seawater duty. The threaded lug body design allows for secure bolting to the pipeline flange without requiring nuts on both sides, making it ideal for end-of-line service or easy removal during maintenance.
Built to Resist from the Inside Out:
-
Body & Coating: Ductile iron with a high-performance marine-grade epoxy coating (standard). Optional stainless steel body available.
-
Disc: Solid naval bronze (C95800) or 316 stainless steel—machined in-house for precision fit and corrosion resistance.
-
Seat & Liner: EPDM (standard) or NBR liner, ensuring a bubble-tight seal and resistance to seawater aging.
-
Pressure & Size: PN10/16,150LB, JIS 5K/10K rating, available from DN50 to DN600.
-
Operation: Manual lever or gearbox (standard). Ready for factory-fitted pneumatic or electric actuators with marine-grade finishes.
Produced under integrated manufacturing control—from material selection and casting to machining, assembly, and testing. Each valve undergoes hydrostatic shell and seat testing to guarantee zero leakage under pressure before it is approved for shipment.
