The Henry F6310 Magni-Chek is a 3/4" ODS magnetic check valve designed specifically for commercial refrigeration and HVAC systems. Unlike conventional spring-loaded check valves which require increasing pressure to lift the plate (causing pressure loss), the Magni-Chek uses magnetic attraction to return the valve plate to its seat. As the plate travels away from the seat, magnetic attraction diminishes, resulting in lower pressure loss and improved system efficiency. Manufactured by Henry Group Industries (established 1914), a global leader in commercial refrigeration and air conditioning components. Henry's Dura Form manufacturing process eliminates braze materials inside the valve body that can overheat and damage internal components during installation. Typical applications: - Commercial refrigeration systems (supermarket racks, walk-in coolers, freezers) - Air conditioning systems using R-410A and compatible refrigerants - Ice machines and refrigerated display cases - Industrial refrigeration MRO NOT for water plumbing, irrigation, hydraulic, or general fluid service. ODS sweat connection is brazed into copper refrigerant lines. Buyer profile: Commercial HVAC/refrigeration service technicians, refrigeration contractors, refrigeration parts wholesalers, and OEM equipment refurbishers.
