Description
Pressure sustaining valve constructed from durable ductile iron, designed to maintain minimum upstream pressure and protect pump systems. Ensures consistent system pressure by automatically opening to relieve excess pressure or closing to maintain set pressure levels. Rated PN16 for pressures up to 16 bar, suitable for medium-pressure applications in water distribution and industrial pipelines. Flanged ends offer secure, standardized connections for reliable installation and straightforward maintenance.
