Protection for low-pressure tanks in a wide range of industries

In all industries in which sensitive process media are used, the highest demands are placed on maintaining the quality, shelf life and product purity of the processed liquid or solid substances. This is often the case in the food industry and in the chemical and pharmaceutical sectors.

The ELEVENT breather valve from REMBE protects vessels with low design pressures against overpressure and vacuum in a pressure range of 2–200 mbarg. This makes it the optimum solution for low-pressure vessels inside storage tanks, dryers and other vessels in the chemical, pharmaceutical and food industries.

For example, ELEVENT is ideal for use in dryers in which free-flowing process media, such as cocoa, raw tablet materials or teas, are processed under vacuum. If the vacuum pressure inside the vessel begins to drop, the valve opens and thus ensures targeted pressure equalisation, which is of immense importance both for the stability of the dryer as well as the quality of the sensitive substances inside.  Controlled maintenance of the pressure level is achieved via a very low leakage rate of up to 1x10^-6 mbar x l/sec. This prevents both emissions of volatile gases or other environmentally harmful substances, as well as the formation of explosive mixtures or a potentially dangerous ingress of air.
