Product Description
Product Description
The 12" Lug Style Butterfly Valve (DN300, ANSI Class 150) is an industrial-grade flow control solution specifically engineered for harsh marine, offshore, and seawater environments. Manufactured with a Ductile Iron JS1030 body, a Nickel Aluminum Bronze (AB2) disc, and a durable NBR seat, this valve offers exceptional resistance to seawater corrosion, cavitation, and mechanical wear.
Equipped with an ISO 5211 top works, an intermediate handwheel operating mechanism, a VSM valve remote transmission device, and a 316SS bracket for linear-to-rotary proximity switches, it provides seamless switching between local manual operation and remote control in inaccessible areas. Fully tested and certified with ABS (American Bureau of Shipping) Type Approval.

Why Choose This Marine Lug Butterfly Valve Assembly?
1. Superior Seawater Corrosion Resistance
The combination of a JS1030 ductile iron housing and an AB2 Nickel-Aluminum Bronze disc makes this 12-inch butterfly valve ideal for seawater intake, ballast systems, and marine cooling lines. The resilient NBR seat delivers zero-leakage bidirectional sealing.
2. VSM Remote Operation for Inaccessible Areas
When installed in deep hull compartments, narrow pipe trenches, or hazardous areas, the integrated VSM remote transmission device allows operators to control the valve safely from a distance via a flexible reach rod/cable system.
3. Integrated Handwheel Manual Override
Featuring standard ISO 5211 top works, the intermediate handwheel operating mechanism ensures smooth manual override capabilities during power losses or routine maintenance without disconnecting the primary actuator.
4. Precision Signal Feedback System
Equipped with a custom 316SS travel converter bracket, the valve accurately translates linear travel signals into rotary switch activation, sending passive dry contact status feedback directly to your shipboard PLC or SCADA system.
5. ABS Certified Quality Assurance
Every unit undergoes rigorous hydrostatic shell, seat leakage, and functional testing witnessed and certified under ABS (American Bureau of Shipping) standards.
Industrial Applications
Shipbuilding & Marine Engineering: Ballast Water Treatment Systems (BWTS), Bilge Stripping, Seawater Circulation, Firemain Lines.
Offshore Platforms & FPSO: Hazardous zone fluids control, deep compartment remote valve operation.
Desalination & Water Infrastructure: High-salinity raw water pumping stations and industrial wastewater treatment.
