Industrial VALV-00671 Stainless Check Wafer Valve

The VALV-00671 Stainless Check Wafer Valve is a 20-inch (DN500), Class 150 LB wafer-style check valve with a stainless steel body designed to prevent reverse flow and protect pumps, compressors, and process equipment from backflow in industrial piping. The valve utilizes a swing or dual-plate check mechanism (design dependent) and installs wafer-style between ASME B16.5-compatible flanges for compact inline flow control. Commonly installed in water treatment plants, industrial process piping, HVAC distribution systems, and chemical handling networks, it supports large-diameter applications in water, wastewater, and industrial fluid handling, including municipal facilities, cooling water systems, chemical pipelines, and chilled-water loops.
