Product Description

When the medium flows in the prescribed direction, the disc is subjected to the medium force. When the medium is turned on, the disc is closed because of the weight of the disc and the disc is subjected to the reverse force of the medium, so that the sealing surface of the disc and the valve seat is closed to prevent the medium from flowing back. The sealing surface of the valve body and disc is welded by stainless steel surfacing.
