Double Offset Lug Type Butterfly Valve With WCB/316 Body PTFE Soft Seat
Double Offset Lug Type Butterfly Valve With WCB/316 Body PTFE Soft Seat
Product Features
Carbon steel lug-type double-offset butterfly valves are an ideal choice for low- and medium-pressure industrial piping systems due to the cost-effectiveness of carbon steel, the convenience of lug connections, the low-wear characteristics of the double-offset design, excellent sealing performance, and broad material compatibility. With advantages such as efficient installation and maintenance, long service life, and energy efficiency, these valves are widely used in the petrochemical, water treatment, and power generation industries. Whether addressing high-temperature and high-pressure operating conditions or implementing automated fluid control, this valve provides a reliable solution and serves as a critical piece of equipment for ensuring the safe and efficient operation of industrial systems.
Product Advantages
●Carbon steel offers a cost reduction of over 30% compared to stainless steel while maintaining sufficient strength and temperature resistance, making it ideal for budget-sensitive projects.
●Easy installation and maintenance: The lug design allows for in-service disassembly and seal replacement without the need to shut down the pipeline, significantly reducing downtime.
●Long service life and reliability: The double-offset design reduces friction and minimizes wear on the sealing surfaces, ensuring a service life of up to 5 years (e.g., in high-temperature conditions in the petrochemical industry).
●Excellent Sealing Performance: Soft-seal leakage rate ≤0.01%; hard-seal performance meets ISO 5208 Class V standards, satisfying zero-leakage requirements in demanding operating conditions.
●Energy Efficiency: Low flow resistance coefficient (only one-third that of a gate valve) and large flow area when fully open, reducing pumping energy consumption by more than 15%.
