Rocker Valve Impulse Version Energy Savings and Compact Design
The fluid technology specialist Bürkert has introduced the first rocker valve as impulse version (bistable). The impulse version of the Type 6624 valve allows energy savings in a compact design in comparison with monostable valves and also features good flushability.
The new valve consumes no energy after the switching process, which is explained by the valve’s functioning principle: a standard rocker valve has two seats, which are opened and closed as a result of electric current.
However, they return to their original state as soon as the current is discontinued. Not so with the pulse version: a current pulse is used only to open a seat, for example – afterwards, it retains its position without the supply of power. This is made possible by a permanent magnet that attracts the iron core of the rocker valve. The valve can be returned to its original state by means of another current pulse.
