Floating Roof Drain Valve

The large knob makes these drainage valves easy to grip.

Floating roof drain valve. Ateco float check valve is designed to operate inside of the drain sump in connection with complete drainage systems. 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. Under normal operating conditions the roof drain valve is open. 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.

A drain guard system is composed of a receiver baffle configuration sensor automated control valve and discharge port. The sumpmaster tm addresses several problems with traditional check valves including more effective sealing at the potentially lower pressures. Or leak preventing devices are installed. Install them at low points in your line after separators dryers filters and aftercoolers.

In use drain guard system. Water drain from floating roofs. For technical drawings and 3 d models click on a part number. A problem still largely solved by nothing more advanced than a manual open roof drain valve.

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. The sumpmaster tm is a sturdy sump valve designed to prevent product flow onto external floating roofs from drain system failures. So it prevents overflow. Of hydrocarbon storage tanks.

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. 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. 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. Not only is this operation incongruous in today s industrial setting.

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 can be serviced without removing them from your air line. Has a potential risk when no oil leak detecting. Also known as drip legs these drain valves have a float that automatically opens the drain when the bowl begins to fill.
