Google valve with new electric actuator


The google valve was a part of an order for the supply of all shut –off and modulation dampers required for the blast furnace gas fired boiler unit 4 of the Mittelsbühren powerstation. The product should be gastight and the Customer seeked to lower the maintenance requirements of equipment without creating additional risk in the plant operation.


We supplied the google valve with gas tight casing. Moreover, per Customer’s request, we utilized a new developed type of electric actuator. Therefore, the retractable sealing frame and the blind and hollow disc are driven electrically.


The shut – off is comparable to that of a blind flange connection in terms of the UVV regulations. The valve has been DVGW approved. Usage of the new type of electric actuator lowered the maintenance costs of the valve.
