Gemu 2" Straight Thru Diaphragm Valve with Flush 798-U Stainless Steel 316L 5PN5 SFV5

The Gemu 2" Straight Thru Diaphragm Valve with Flush (model 798-U) is a high-purity, aseptic valve designed for biopharmaceutical, semiconductor, and food processing applications. Constructed from 316L stainless steel with ASME BPE compliance, it ensures hygienic operation and resistance to corrosion in demanding environments. The straight-through design minimizes pressure drops and facilitates easy cleaning, while the flush port allows for efficient sterilization and drainage, reducing contamination risks. Key features include a manual actuator with a black handle for precise control, EPDM or PTFE diaphragm options for compatibility with various media, and a compact, lightweight build for easy integration into piping systems. Advantages over similar products include superior surface finish (SFV5 electropolished) for ultra-clean processes, low maintenance due to the weirless design, and compliance with stringent standards like USP Class VI. Benefits include reliable shut-off, minimal dead space, and high cycle life, though drawbacks may involve higher initial cost compared to basic ball valves and the need for periodic diaphragm replacement in aggressive media. This valve excels in sterile processes, offering better flow characteristics and hygiene than traditional globe valves. Based on image analysis, the unit appears new with no visible wear, clean engravings including '316L 1.5PN5 798-U SFV5 GEMU ASME BPE', and no attached child assets. Estimated market price for a new unit is $700-900 USD, based on comparable listings from suppliers like Cole-Parmer and eBay.
