2-Way High Performance Butterfly Valve

The Belimo 2-Way High Performance Butterfly Valve combines an innovative disc profile with an advanced resilient seat design to provide outstanding shut-off performance and highly accurate flow control for HVAC and industrial fluid handling systems.

Its specially engineered disc and seat design ensure reliable sealing across a broad pressure and temperature range. Under low-pressure and vacuum conditions, the resilient seat generates additional sealing force to maintain tight shut-off performance. At higher operating pressures, the seat geometry is designed to guide and control seat movement toward the disc edge, ensuring consistent sealing while maximizing valve durability.

Designed specifically for HVAC and commercial building services, this high-performance butterfly valve is ideal for applications requiring dependable shut-off under elevated operating pressures and temperatures.

Typical applications include:

Chilled water isolation systems
Cooling tower systems
Changeover systems
Process control applications
Flow diversion and bypass systems
Large air handling units (AHUs)
District cooling systems
Industrial fluid handling systems

Its high flow coefficient (Cv) provides an economical and reliable solution for large-volume flow applications while maintaining excellent control accuracy and energy-efficient operation.

Available Sizes

Belimo High Performance Butterfly Valves are available in sizes ranging from DN80 to DN800, providing dependable flow control solutions for commercial buildings, district cooling systems, and industrial process applications.
