LEDE 6″ (DN150) Ductile Iron Wafer Butterfly Valve with Built-in Tamper Switch ? PN16/300 PSI

Description
The LEDE Model LV3141-150 is a space-saving isolation valve designed for fire sprinkler and industrial water systems. The Wafer Type design allows the valve to be “sandwiched” between two standard pipe flanges (PN16 or ANSI), making it significantly lighter and more compact than traditional gate valves.
This valve comes standard with a heavy-duty Gear Operator, providing smooth opening and closing while preventing water hammer. It is uniquely equipped with an Integrated Tamper Switch (Supervisory Switch) housed within the gear box. This pre-wired assembly simplifies installation, providing immediate signals to the Fire Alarm Control Panel (FACP) if the valve is moved from the fully open position.

Key Features
Integrated Monitoring: Includes a factory-installed, internal dual-contact tamper switch for supervisory signaling.
Space-Efficient: Compact wafer design reduces the overall footprint and weight of the piping assembly.
Bubble-Tight Shut-Off: The ductile iron disc is fully encapsulated in EPDM rubber, ensuring a leak-proof seal and low torque operation.
Durable Gearbox: Features a weather-resistant handwheel gear operator with a clear visual position indicator (Open/Closed).
Corrosion Resistance: The body is finished with a high-visibility, Red Fusion Bonded Epoxy (FBE) coating.
Safety Approved: Fully UL Listed and FM Approved for use in fire suppression service at a working pressure of 300 PSI.
