The valve body has a lateral inlet connection and is fitted with a seat welded in place which can be exchanged, and has a close fitting expansion cone. The valve stem and cone are made in one piece. The stem is mounted to be free from vibration and is guided in a bush in the valve cover and another bush in the valve core. Cover and valve are fastened together by a clamping device which facilitates assembly.

The noise level is kept low because of a special design of internal parts. The pulse from the control unit causes the valve drive to change position of valve cone. The gap between the seat and the cone allows the medium to flow. The valve can be opened against the pressure of the medium. A complete seal in the closed position is secured.
