Product characteristics :
The butterfly valve should be used for open, close and regulating medium flow in pipeline of petroleum, chemical,food, medicine, metallurgy, ship, can also be used in a variety of corrosive medium, The following feature:
1. Excellent bidirectional sealing performance, Minimized operation torque.
2. Flow characteristics tend to be straight, good regulation performance.
3. Choosing different materials, can be used in corrosive medium.
4. Simple and compact structure, compact and light, easy to transport, install and disassemble.

Our 2.5 inch butterfly valve is a professional-grade flow control solution specifically engineered for the demanding requirements of fire protection systems. Designed with a robust lug type wafer butterfly valve configuration, this unit provides secure, reliable installation between pipe flanges, ensuring optimal structural stability in critical piping networks.
Equipped with an intuitive lever butterfly valve mechanism, this valve allows for rapid, manual control of fluid flow. The ergonomic handle butterfly valve design facilitates quick opening and closing, which is essential for efficient system management and emergency response in commercial or industrial fire suppression setups. Every valve is manufactured to meet rigorous quality standards, ensuring a bubble-tight seal that prevents leakage and maintains necessary system pressure.
This fire-rated butterfly valve is constructed from durable, high-strength materials selected for their longevity and resistance to the harsh conditions often found in industrial environments. The compact, space-saving wafer design makes it an ideal choice for installations where space is limited, without compromising the valve's overall performance or flow capacity.
We are dedicated to providing high-performance fluid control solutions that support your B2B infrastructure projects. Whether you are replacing components in an existing fire system or configuring a new installation, our 2.5 inch butterfly valve offers the dependability and ease of operation required for high-stakes safety applications. Our team provides full technical support to assist you with material selection, pressure ratings, and custom configurations to match your specific piping requirements.
