This Honeywell Butterfly Valve is a non-conductive, 24-volt, two-position device with a three-inch lug. The butterfly valve, often abbreviated as Btrfly Vlv, is designed to control the flow of fluid in a pipe or tube by using a disc positioned in the center of the pipe. The disc, which forms the 'butterfly' component of the valve, is rotated by an actuator to either block or allow flow. This particular model from Honeywell operates at 24 volts (24V) and has two positions (2POS), meaning it can be set to either fully open or fully closed. The term 'non-conductive' (N/C) indicates that this valve does not conduct electricity, making it safe for use in environments where electrical conductivity could pose a risk. Finally, the three-inch lug (3"LUG) refers to the size and type of connection used to attach this valve to a pipe or tube.
