Floating Roof Drain Valve

When the stainless ball floats inside of the valve the drain systems will be closed.

Floating roof drain valve.

Function and description 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. Water drain from floating roofs. Drains can be serviced without removing them from your air line. Primarily designed for floating roof storage tank drain systems tank farm dike drain systems and wastewater treatment facilities spill stoper remains open during normal operation allowing rainwater and non hydrocarbon liquids to flow and drain from the tank or dike area.

Float valves for draining condensate automatically remove condensate from compressed air or inert gas lines these float valves have a float operated drain control. Drains are required to have a check valve near the roof to prevent backflow of the liquid stored in the tank in the event of leakage into the drain api 650 appendix c para graph c 3 8. Also known as drip legs these drain valves have a float that automatically opens the drain when the bowl begins to fill. So it prevents overflow.

However should hydrocarbons enter the liquid flow the internal sensing characteristics of the spill stoper cause it to close containing the problem and protecting the environment. Roof drain float check valve 1. The large knob makes these drainage valves easy to grip. Section 630 covers roof drains in more detail.

A drain guard system is composed of a receiver baffle configuration sensor automated control valve and discharge port. Under normal operating conditions the roof drain valve is open. The float therefore floats all the time and if a rain event happens the valve allows the rain to flow from the roof to via the internal drain mechanism and out through the belfield valve. Has a potential risk when no oil leak detecting.

The drain guard system alerts an owner or operator of hydrocarbons present in floating roof drains diked areas or similar applications thus reducing risk and protecting inventory. Of hydrocarbon storage tanks. The sumpmaster tm addresses several problems with traditional check valves including more effective sealing at the potentially lower pressures. A problem still largely solved by nothing more advanced than a manual open roof drain valve.

The sumpmaster tm is a sturdy sump valve designed to prevent product flow onto external floating roofs from drain system failures. Or leak preventing devices are installed. In the event of a leaking joint or drain hose the belfield valve will sense the changing gravity and close. For technical drawings and 3 d models click on a part number.

Ateco float check valve is designed to operate inside of the drain sump in connection with complete drainage systems.
