Lug Style Butterfly Valve
Lug Style Butterfly Valve Manufacturer
MVS Valves Lug Style Butterfly Valve is engineered for high performance and reliability across diverse pipeline systems, ensuring uninterrupted flow control in industrial, commercial, and utility-grade applications. Designed in compliance with API 609 and MSS-SP-67 standards, this lug type butterfly valve features a durable cast-body with precision-threaded lugs, allowing secure installation and dead-end service without the need for downstream flanging. Its compact body fits seamlessly in tight piping layouts, while the centrally mounted disc guarantees optimal sealing with minimal torque.
Available in a wide size range from DN 50 to DN 1200, the valve supports working pressures up to 150 psi and can be operated manually or automatically through lever, gearbox, pneumatic, or electric actuation methods. It is ideally suited for water distribution, HVAC systems, chemical processing, and low-pressure gas pipelines. What sets MVS apart is the integrally moulded body with exceptional seat retention and sealing integrity.
Every Lug Style Butterfly Valve is manufactured with the industry’s most trusted materials including Carbon Steel, SG Iron, and Stainless Steel (CF8 and CF8M). These options provide excellent corrosion resistance, mechanical strength, and compatibility with aggressive media. For enhanced sealing reliability, the valve comes with a variety of resilient rubber liner seat options like Black Nitrile, EPDM, Viton, Hypalon, and Silicon, ensuring performance across a wide range of temperatures and fluids.
In addition, the valve is equipped with a stainless steel pad per ISO 5211, allowing easy integration with standardized actuators and mounting systems. This makes it highly versatile for automated flow control operations in demanding industries. Whether it’s in municipal water projects, thermal fluid systems, or light chemical applications, the lug type butterfly valve from MVS Valves is designed to deliver exceptional flow control, resistance to wear, and long-term durability.
MVS Valves is committed to delivering superior butterfly valve technology by combining expert engineering, precision manufacturing, and strict quality testing. Each valve is carefully checked for leak-tight performance and durability, ensuring that customers receive only the best in flow management solutions.
