Butterfly Valves

Water and wastewater systems
Butterfly valves are used in water and wastewater networks for isolation and flow control. They are installed on pump discharge lines for quick shutoff. They regulate flow in treatment plant pipelines, such as sedimentation, aeration, and sludge handling. They help separate zones during maintenance within distribution systems.

HVAC and building services
Butterfly valves are used in HVAC systems for isolating and regulating chilled water, hot water, and condenser water circuits. They are typically installed at pump suction and discharge lines, across heat exchangers, and on AHU coil connections, allowing equipment maintenance without draining the whole loop. With electric actuators, they connect directly to building management systems for automated flow control and precise temperature regulation.

Chemical and process industry
Butterfly valves are used in pipelines carrying cooling water, process water, acids, solvents, and some slurry streams. They function as isolation valves for maintenance, throttling devices in mixing or reaction loops, and block valves on storage tank inlets and outlets. Their compact design makes them practical on large process headers and in congested pipe racks.

Compressed air and gas systems
Butterfly valves are ideal for emergency shutdowns and fire suppression systems where quick isolation is critical. They are typically placed at compressor discharges, receiver tank outlets, and main pipelines for rapid shutoff, and at branch connections to isolate plant sections without shutting off the entire network.

Potable water systems
Butterfly valves are used in potable water networks for isolation and flow regulation in transmission and distribution pipelines. They are installed at pump discharges, treatment plant outlets, storage reservoirs, and distribution mains to allow maintenance without interrupting supply. On branch lines, they help control flow and isolate zones during repairs.
