2General information

Features and applications

TVD. breather caps with vacuum breaker valve are suitable for reservoirs and tanks for liquid transport.

The membrane retaining system allows a quick emptying out of the reservoir by letting in big quantities of air through the cap. Thus avoiding the vacuum inside the reservoir, slowing down the liquid exit.

The pre-set pressure of the membrane gasket stops any liquid loss when the reservoir is shaken (for example during transportation).

The liquid pressure on the gasket guarantees a perfect seal of the cap, for example in case of overturning of the reservoir.

Resistance to chemical agents

Tests carried out under standard laboratory conditions at 23°C. Values to be considered only as guidelines.

Please contact ELESA Technical Department for further chemical resistance details to particular liquids not reported in the table.
