A 150 mm butterfly valve is a quarter-turn rotary valve used to control, throttle, or isolate fluid flow in large-diameter piping systems. It features a flat or slightly profiled disc that rotates about a central shaft to block or admit flow. Butterfly valves are valued for their compact design, quick operation, and cost-effective performance in water, air, and various fluid applications.
Key Features
• Size:
Nominal diameter 150 mm (equivalent to DN150 or approx. 6 inches).
• Operation:
Quarter-turn mechanism (90° rotation) allows quick opening and closing — usually by lever, gear, pneumatic, or electric actuation.
• Body & Disc Materials:
Common materials include cast iron, ductile iron, carbon steel, stainless steel (SS304/SS316) — choice depends on fluid type, pressure, and corrosion resistance requirements.
• Seal/Seat:
Elastomer lining like EPDM, NBR, Viton, or PTFE seats improve sealing and minimize leakage.
• Connection Type:
Typically wafer, lug, or flanged designs to fit between mating pipe flanges.
• Pressure & Temperature:
Available in various pressure classes (e.g., PN10, PN16, PN25 or ANSI Class 150) with typical temperature ranges from around -20 °C to 150 °C depending on materials and seat types.
