They close instantly upon contact with the stored product, thereby eliminating the risk of pollution and product loss.

TOR model: for the evacuation of rainwater accumulated on floating roofs. TOO model: for the automatic draining of water at the bottom of tanks.

Benefits

Enhanced safety: reduces the risk of hydrocarbon spills and vapor exposure
Targeted water drainage without loss of stored product
Eliminates operator contact with the product
No external power required
Low maintenance and long service life
Optimizes storage space (TOO model)
Protects the floating roof from corrosion and prevents sinking (TOR model)

Avantages

Installation

TOR: installed on the floating roof drain nozzle to evacuate rainwater.

TOO: installed on the tank bottom purge nozzle to automatically drain settled water.

Standard connection via 4” ANSI #150 RF flange (B16.5 standard). Simple and quick installation without the need for external control systems.

Technology

Both models operate without electricity.
Based on product density, an internal float allows water to pass and closes immediately upon contact with hydrocarbons.
An integrated strainer ensures tightness and blocks contaminants.
An anti-vortex system optimizes the drainage flow without disruption.

Testability

Trigger tests can be performed by simulating hydrocarbon entry.
Simplified maintenance thanks to easy access to internal components.

Options

TOO: Possibility to reinject the stored product from the valve directly back into the tank via a pump.
TOO: Option for a visual indicator of the float position.
TOR: Option for valve status feedback in the control room.
TOR: Available with valve insulation (heat tracing).
