The BFV761-Series is a pneumatically actuated wafer-type butterfly valve built for automated on-off and modulating flow control in industrial pipelines. Powered by compressed air, its single or double-acting actuator delivers 90° disc rotation within 0.5–3 seconds for rapid response. Featuring a compact wafer body for direct flange-to-flange mounting, the valve adopts a fully rubber-encapsulated disc to achieve zero-leakage soft sealing, reliable bidirectional sealing performance and low flow resistance. Compatible with standard automation accessories like solenoid valves and positioners, it is widely deployed in water and wastewater, fire protection, HVAC and industrial process systems, covering sizes from NPS 2 (DN50) to NPS 12 (DN300) with PN16 pressure rating.
