Function and Description
Roof Drain Valve for Floating Roof Drainage Systems
The PROTEGO® Roof Drain Valves D/SR or D/SR-W have the function of an inlet cup, which collects the rainwater from the floating roof through the scissor pipes of a PROTEGO® Floating Roof Drainage System, e.g., SE/K or SE/CK, into the sewage system.
Protection Against Debris, Leaves, and Nesting Birds
Under normal operating conditions, the roof drain valve is open. In case of any leakage, the non-return valve prevents the stored substance from escaping to the floating roof. The inlet screen protects the roof drain valve from any dirt, leaves, or nesting animals.
