Description
    The Sporlan Type DDR differential pressure regulating valves have a cast iron painted body with copper connections and the (O)LDR) differential pressure regulating valves have a brass body with copper connections. These valves are adjustable. The DDR creates a differential pressure between its inlet (discharge) pressure and the receiver pressure to allow reverse flow during the defrost cycle. The (O)LDR creates a differential pressure between the receiver and liquid header to allow reverse flow during the defrost cycle. Each valve is factory tested to ensure positive leak-free performance.

    Markets:
    • Refrigeration

    Features/Benefits:
    • Able to maintain a differential pressure between the defrost header and the liquid header, allowing reverse flow during the defrost cycle.
    • Combines a liquid differential valve and a solenoid valve into one component, thus reducing piping costs.
    • Ability to adjust the differential setting.
    • Design working pressure for the DDR and (O)LDR valves is 400 psi (27.6 bar),

    Applications:
    • Refrigeration – Supermarket racks
