High Performance Double Offset Wafer Butterfly Valve (Carbon Steel)

High-Performance Double Offset Butterfly Valve – Precision Control with Long-Term Reliability

The High-Performance Double Offset Butterfly Valve from BM Engineering Supplies delivers superior sealing, low-friction operation, and extended service life for demanding process applications. Its double eccentric disc design lifts the disc off the seat during operation, reducing wear and enabling reliable sealing under higher pressures and temperatures.

This wafer-pattern valve fits compactly between flanges, making it ideal for space-saving installations in pipelines. With robust construction, low torque requirements, and compatibility with actuation systems, it is well-suited to industrial sectors including chemical processing, water treatment, HVAC, and marine engineering.

🔧 Key Features & Benefits:

• Double Offset Disc Design: Reduces friction and seat contact, improving seal integrity and valve longevity

• Wafer Body Pattern: Space-efficient installation between flanges (conforms to industry flange standards)

• Low Operating Torque: Ideal for manual, electric, or pneumatic actuation with reduced energy requirement

• Durable Construction: Commonly available with stainless-steel or duplex discs and PTFE, RPTFE, or metal seats

• High Performance Range: Typically suited for pressures up to PN16–PN25 or ANSI Class 150–300 (confirm per spec)

• Automation Ready: ISO 5211 top flange enables direct mounting of actuators for remote or automated operation

• Versatile Media Handling: Suitable for liquids, gases, and steam across multiple flow control systems

🏭 Industry Applications:

• Water & wastewater treatment – corrosion resistance and low-maintenance operation

• Chemical and petrochemical – suitable for aggressive or corrosive process media

• Marine & offshore – compact footprint and durable sealing performance

• HVAC systems & energy plants – reliable shut-off and control for chilled or heated water

• Power generation – high-pressure resilience and actuator adaptability
