초록

The present invention relates to a double poppet valve comprising two independently movable valve heads cooperating with a valve seat located in a valve housing between an inlet duct and an outlet duct for a liquid product, and enclosing therebetween in the open position as well as in the closed position a leak control space adapted to be sealed in the open position of the valve to reduction of the distance between the two valve heads caused on opening of the valve by one of the valve heads being advanced so as to engage the other valve head at the end o...
