About Butterfly Valve
Butterfly valve is a type of quarter-turn valve used to regulate or shut off the flow of liquids or gases in a pipeline. The valve consists of a circular disc or plate with a pivot in the center, which is connected to an actuator (such as a lever or gear) outside the valve body. When the actuator is rotated 90 degrees, the disc turns to open or close the valve. Butterfly valves are commonly made from materials such as cast iron, steel, or PVC, and are available in a variety of sizes and pressure ratings to suit different applications. They offer several advantages over other types of valves, including quick and easy operation, low pressure drop, and minimal leakage.
Versatile Performance Across IndustriesEngineered to meet EN 593 and API 609 standards, this butterfly valve excels in industrial, HVAC, water supply, and firefighting applications. Its robust construction and precise design ensure reliable operation in demanding environments. The blue epoxy-coated cast iron body and stainless steel disc resist corrosion, granted leak-tight security (Class VI), making it an ideal solution for controlling water, air, oil, or gas flow safely and efficiently.
Exceptional Leak Proof ReliabilityFeaturing EPDM or NBR seat materials and tested to Class VI (bubble tight) leakage standards, this valve delivers outstanding sealing integrity. The precise valve design, combined with stainless steel stem and disc, ensures longevity and dependable service even under fluctuating pressure and temperature conditions. Suited for flanged pipe systems with convenient wafer (lug type) connections, this valve guarantees peace of mind in critical operations.
