Industrial 2478D-DA Relief Valve

Industrial 2478D-DA Relief Valve from Dresser is an automatic overpressure protection device that vents fluid when system pressure reaches its preset limit, helping safeguard vessels, piping, and equipment in industrial processes. The 2478D-DA designation identifies this specific model within Dresser's lineup of relief valves, a family of safety devices designed for use in process and utility systems. Relief valves perform without external actuation, opening to relieve excess pressure and then resealing once the threat subsides to restore normal operation. For proper selection, installation, and maintenance, consult the official datasheet and Dresser guidance to confirm compatibility with your system's fluids and service conditions, and to ensure compliance with applicable safety standards. This model is part of industrial safety equipment used to maintain pressure integrity in fluid systems.
