Industrial VALV-00671 Stainless Check Wafer Valve

Description:

The VALV-00671 Stainless Check Wafer Valve 20-IN 150-LB Check Valve is used in industrial piping systems to prevent reverse flow and protect pumps, compressors, and process equipment from backflow damage. It is a wafer-style swing or dual-plate check valve designed for installation between ANSI Class 150 flanges, providing compact in-line flow control in high-capacity pipelines. Commonly installed in water treatment plants, industrial process piping, HVAC distribution systems, and chemical handling networks. Maintenance teams, OEM manufacturers, and system integrators use this part for replacement of failed check valves, retrofit of pipeline systems, and restoration of proper one-way flow control in high-volume industrial applications.

Applications:

The VALV-00671 Stainless Check Wafer Valve 20-IN 150-LB is used in large-diameter piping systems to prevent backflow in water, wastewater, and industrial fluid handling networks. It is commonly applied in municipal water treatment facilities, industrial cooling water systems, chemical processing pipelines, and HVAC chilled water loops where reliable non-return flow protection is required.
