Pressure Regulating Valve - Defrost Differential - Sporlan - DDR, (O)LDR

Pressure Regulating Valve - Defrost Differential - Sporlan - DDR, (O) LDR

Brand: Sporlan
Add Product to My Catalog

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. 

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.
Features
  • 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)
