Butterfly valve BFV-300 series

with handwheelfor controlpipe

General DescriptionThe TYCO Models BFV-300 and BFV- 300C Grooved End Butterfly Valves are indicating type valves designed for use in fire protection systems where a visual indication of open or closed valve condition is required. They are used, for example, as system, sec- tional and pump water control valves. They have grooved inlet and outlet con- nections that are suitable for use with grooved end pipe couplings listed or approved for fire protection systems. For applications requiring supervi- sion of the open or closed state of the valve, the Gear Operators for the Model BFV-300/BFV-300C Butterfly Valves feature two sets of factory installed internal switches each having SPDT contacts, see Figure 3. The supervisory switches transfer their electrical con- tacts when there is movement from the open or closed disc position during the first two revolutions of the handwheel.
