Butterfly Valve PN10
What is a Butterfly Valve PN10?
A Butterfly Valve PN10 is a quarter-turn valve designed to regulate, isolate, or throttle fluid flow in pipelines. It uses a circular disc mounted on a rotating shaft that turns 90° to fully open or close the flow. The “PN10” rating indicates the valve’s pressure handling capacity of up to 10 bar, making it suitable for low to medium pressure applications.
Asaid Steel Industries, a trusted Butterfly Valve PN10 manufacturer and supplier in Pune, India, offers robust and durable valves designed for leak-tight performance in water treatment, oil & gas, chemical processing, and HVAC applications. Available in cast iron, ductile iron, stainless steel, and carbon steel, our PN10 butterfly valves are engineered as per API 609, EN 593, and ISO standards, ensuring long service life, easy installation, and low maintenance. With options in wafer, lug, and flanged end connections, we are recognized among the leading industrial valve suppliers in India for delivering reliable, cost-effective, and high-performance solutions.
