General
Description
The TYCO Model BFV-N Wafer Style Butterfly Valves (Ref. Figure 1) are indi-cating type valves designed for use in fire protection systems where a visual indication is required as to whether the valve is open or closed. They are used, for example, as system, sectional, and pump water Control valves. They are suitable for installation between ANSI Class 125 or 150 flanges without the need for flange gaskets.
For applications requiring supervision of the open position of the valve, the Gear Operators for the Model BFV-N Butterfly Valves are provided with two sets of factory installed internal switches each having SPDT contacts. The supervisory switches transfer their electrical contacts when there is move-ment from the valve's normal open posi-tion during the first two revolutions of the handwheel.
NOTICE
The TYCO Model BFV-N Wafer Style Butterfly Valves described herein must be installed and maintained in compli-ance with this document, as well as with the applicable standards of the National Fire Protection Association, in addition to the standards of any Other authori-ties having jurisdiction. Failure to do so may impair the performance of these devices.
The owner is responsible for maintaining their fire protection system and devices in proper operating condition. Con-tact the installing contractor or product manufacturer with any questions.
