V74 040 B9B 498DAH
DN 40 1.5" SS 304 Butterfly Valve
The V74 040 B9B 498DAH DN40 (1.5") SS304 Butterfly Valve is a quarter-turn industrial butterfly valve designed for flow isolation and regulation in piping systems. Constructed primarily from Stainless Steel 304, it offers excellent corrosion resistance, durability, and reliable sealing performance for water, air, gases, and compatible process fluids. The valve utilizes a rotating disc mechanism that provides fast opening and closing with low operating torque, making it suitable for manual or automated operation.
