Vulcan 68330 Flanged Pressure Relief Valve WCB

The Vulcan 68330 Flanged Pressure Relief Valve is a spring-loaded device that automatically relieves overpressure in industrial piping, vessels, and process equipment, providing automatic overpressure protection in process plants, boiler systems, chemical processing equipment, and fluid handling systems with flange mounting and a 1-1/2 in × 2-5/8 in connection size. It features a WCB cast carbon steel body and is designed for compatibility with liquids, gases, and process fluids, operating on an automatic pressure relief and reseating principle to protect equipment and maintain process safety. The unit is intended for periodic inspection, testing, and calibration verification as part of maintenance routines and is commonly used in process control systems and industrial safety applications. For replacements or retrofits, compatible alternatives include Crosby J-Series, Kunkle Series 6000, and Farris Series 2600, making it suitable for integration into existing safety relief valve assemblies.
