D/SR & D/SR-W Roof Drain Valve

The Protego roof drain valves D/SR or D/SR-W function like collection bowls and pass the collected rain water from the floating roof through the scissor pipes of a Protego floating roof drainage system, such as SE/K or SE/CK, into the sewage water system. 

Under normal operating conditions the roof drain valve is open. 

In case of any leakage the non-return valve prevents the stored medium from escaping to the floating roof. 

The inlet screen protects the roof drain valve from any dirt, leaves or nesting birds.
