Mastering Flow Control with Lug Type Butterfly Valves

As a premier leader in industrial valve manufacturing, we specialize in providing high-performance solutions centered around valve types and operation. Our Lug Butterfly Valves are engineered for superior sealing and structural integrity, offering a critical advantage for end-of-line services and dead-end applications where isolation is paramount.

By integrating advanced materials like ASTM A351 Stainless Steel and diverse seating options (PTFE, Viton), our valves ensure compatibility with wide-ranging fluid media. The technical edge lies in our threaded insert design, allowing independent bolting of flanges for enhanced maintenance flexibility and significantly reduced operational downtime.

Frequently Asked
Questions

Expert answers to common technical and commercial inquiries.

What is the primary difference between Lug and Wafer butterfly valves?

Lug valves feature threaded inserts that allow them to be bolted independently to flanges, making them ideal for valve types and operation in end-of-line services. Wafer valves are clamped between flanges and require both sides to be connected.

Which seat material should I choose for chemical applications?

For aggressive chemical fluids, PTFE is highly recommended due to its exceptional inertness. For general industrial use with moderate temperatures, EPDM or Viton are excellent choices.

Can Lug butterfly valves be automated?

Yes, our valves are fully compatible with pneumatic and electric actuators. We offer tailored mounting kits to ensure seamless integration with your control system.

What are the available size ranges?

We provide a comprehensive range from 1.5" to 48", catering to both compact industrial lines and large-scale municipal water infrastructure.

Do you comply with international flange standards?

Yes, our valves are designed to be compatible with ANSI, DIN, JIS, and BS flanges, ensuring easy installation globally.

How do I determine the correct valve for my pipeline?

You should consider fluid type, pressure rating, temperature, and maintenance needs. Our technical team is available to provide one-on-one guidance for the perfect configuration.
