AL/DK & AL 200 Lift-Actuated, Vent Valve

Brand: PROTEGO
Protego lift-actuated vent valves type AL/DK provide automatic venting of floating roof tanks when the floating roof is lowered on its supports and the tank is either finally drained or refilled.

When the floating roof is in its lowest position the valve is forced to open through lift actuation and this prevents unacceptable vacuum during final draining or unacceptable pressure during refilling.

Lift-actuated vent valves Protego AL 200 can be applied in case just venting is required.
