Sanitary Check Valve

This sanitary check valve is manufactured from high-quality AISI 304 or 316L stainless steel with smooth internal surface finishing Ra 0.8m, featuring zero-dead-angle flow-path design to avoid medium residue. It automatically prevents back-flow of process media in piping systems, supporting CIP clean-in-place and SIP sterilize-in-place requirements. Available in welded, tri-clamp and union connection types, it is widely applied in food & beverage, dairy, biopharmacy, fine chemical, lithium-battery and pure-water treatment industries. Multiple structural options including ball-type, wafer-type and lift-type are offered to suit different working pressure, flow rate and installation conditions, with FDA-compliant sealing components for reliable, long-term hygienic service.
