Automatic recirculation valves ensure automatic gas venting when the pumps are not in operation. The drive and motor capacity can be significantly lower, which in turn has a positive effect on energy consumption and the system costs.

The SMV multifunctional valve is a product innovation for avoiding problems well-known in practical operation. The aim of this development is to ensure system safety and availability by means of cost-optimised functional bundling. Automatic venting makes a meaningful contribution to pump protection in addition to minimum volume control and the return function in the main pumping volume.

The main application range lies in the process engineering of particularly technical liquid gases, especially at low temperatures, as well as in tank storage technology and the loading of liquid gases. In addition, the SMV multifunctional valve is particularly well suited to all pump systems that pump liquids at a temperature close to their boiling point, for pumping two-phase mixtures, for pumping gaseous media and for pumps equipped with gas injection with the aid of modern sealing systems or similar devices. Canned motor pumps and magnetic pumps protect the multifunctional valve against running dry.
