Understanding Butterfly Valve SealsWhat are Soft Seals?Soft seals in butterfly valves are typically made from elastomeric materials such as EPDM (Ethylene Propylene Diene Monomer), NBR (Nitrile Butadiene Rubber), or PTFE (Polytetrafluoroethylene). These materials provide excellent sealing properties
Understanding Butterfly Valves in Water Treatment SystemsStructure and FunctionButterfly valves are quarter-turn valves that use a flat disc mounted on a rotating stem to control the flow of fluids. The disc rotates to open or close the valve, and it remains in the flow path even when the valve is f
Understanding EN 593 StandardScope and ApplicabilityEN 593 is a European standard that specifies the minimum general requirements for metallic butterfly valves used in various applications, including water supply and wastewater treatment. The standard covers a wide range of sizes and pressure rating

In the modern industrial field, pipeline systems are like the blood vessels of the human body, responsible for transporting various fluid media. As a key component in pipeline systems, the performance of valves directly affects the operational efficiency and safety of the entire system. The centerli
