Wholesale Butterfly Valve for Reliable Flow Control in Industrial Pipelines

The Electric Ventilation Butterfly Valve is designed for airflow control in ventilation ducts, exhaust systems, dust collection lines, and industrial hot-air applications. Combining an electric actuator with a butterfly valve body, it supports remote on/off operation and, with a compatible modulating actuator, adjustable airflow control.

The Electric Grooved Butterfly Valve is designed for automated flow control in fire protection, HVAC, building water supply, and industrial water circulation systems. Its grooved connection allows convenient installation and maintenance, while the electric actuator supports remote on-off operation or modulating control, depending on the selected configuration. Liangfa offers multiple body, disc, stem, and seat materials to suit different media and operating conditions.

The Electric Flanged Butterfly Valve from Liangfa is designed for remote pipeline shutoff and flow control in water supply, HVAC, wastewater treatment, and industrial utility systems. Its soft-seated design, multiple material options, and configurable electric actuators support different operating conditions and automation requirements.

Liangfa’s Electric Wafer Butterfly Valve is designed for automated shutoff and flow control in HVAC, water supply, drainage, and industrial pipeline systems. Its compact wafer structure saves installation space, while optional ductile iron or stainless steel components and EPDM, NBR, PTFE, or FKM seats help meet different operating requirements. On-off and modulating actuator options support remote control and flow adjustment.

Liangfa’s Pneumatic Ventilation Butterfly Valve is designed for automated airflow control in industrial ventilation, dust collection, and exhaust duct systems. Its pneumatic actuator supports on-off operation, with optional 4–20 mA modulating control for remote airflow adjustment. Available body, disc, and sealing materials can be selected according to gas composition and operating conditions.

Liangfa's Pneumatic Expansion Butterfly Valve is designed for abrasive powder conveying, industrial dust collection, and flue gas control systems. Featuring an inflatable sealing ring that retracts during disc movement and expands after closure, it helps reduce seal wear, prevent particle jamming, and improve shut-off reliability.
