Въглеродна стомана напълно облицована EPDM вафлена проверка клапан

Engineered for aggressive media, this valve isolates metal from fluids via a seamless EPDM lining. The EPDM-coated disc opens under forward flow and closes elastically against backflow, ensuring zero leakage. The WCB body, fused with EPDM through high-temperature vulcanization, prevents lining delamination even under prolonged chemical exposure. With galvanized, 2Cr13, or stainless steel stems, it adapts to varying corrosive intensities. Its low-resistance flow path reduces pressure loss by 25% versus metal-seated valves, excelling in corrosive slurry transport and wastewater treatment. Manufactured under ISO9001 standards, it delivers рентабилни решения за корозия и уплътняване .

The WCB full-lined EPDM wafer check valve features a WCB cast steel body with a>=5mm-thick EPDM (Ethylene Propylene Diene Monomer) lining, combining structural strength with chemical resistance for PN16 pressure and media<=80℃. The EPDM-coated stainless steel disc achieves bubble-tight bidirectional sealing via elastic deformation, suitable for highly corrosive fluids (acids, alkalis, saline solutions). Stem options include galvanized steel, 2Cr13 stainless steel, or 304 stainless steel, treated for rust prevention in humid environments. ISO 5211-compliant wafer flanges reduce installation thickness by 40%, supporting ANSI, DIN, и други стандарти .
