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 Toit flottant A floating roof is the roof of a tank that is fitted with floating chambers (pontoons) and lies on top of the liquid. 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 Soupape de plafond A roof drain valve is mounted on floating-roof tanks and allows controlled draining of collected rain water into the sewage system via a floating roof drainage system. 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.
