Description
Pressure relief valve manufactured from robust ductile iron, offering excellent strength and corrosion resistance for industrial and municipal applications. Designed to protect piping systems and equipment by automatically releasing excess pressure to prevent overpressure conditions. Rated PN16 for pressures up to 16 bar, suitable for medium-pressure systems. Flanged ends provide secure, leak-tight, and standardized connections, ensuring easy installation and maintenance within pipeline networks.
