EPDM Lined Diaphragm Valve

An EPDM lined diaphragm valve is a linear-motion isolation valve featuring an internal body cavity lined with a thick, robust Ethylene Propylene Diene Monomer (EPDM) elastomer, coupled with a flexible EPDM diaphragm that compresses against a central weir to achieve bubble-tight shut-off. This complete elastomeric lining isolates the metallic valve body from the process fluid, providing broad-spectrum chemical resistance to hot water, mild acids, alkaline solutions, and abrasive slurries, while preventing the accumulation of suspended solids or crystalline materials inside the valve. These highly sanitary, wear-resistant valves are primary specifications in municipal water purification, food processing utilities, and chemical neutralization lines, allowing utility engineers and plant designers to secure non-clogging isolation by importing certified EPDM lined diaphragm valves directly from specialized manufacturers in China via our advanced B2B commercial platform.
