Title (EN) FLEXIBLE METAL SEALING LIP
(FR) LEVRE D'ETANCHEITE METALLIQUE FLEXIBLE
Abstract: front page image
(EN) A low pressure backseat sealing apparatus having a flexible sealing lip which contacts the backseat prior to contact between a stem shoulder and the backseat, with the stem shoulder positioned above the flexible lip, thereby limiting stem movement while allowing internal valve pressure to achieve a seal between the flexible lip and the bonnet.
(FR) L'invention concerne un appareil d'étanchéité de siège arrière basse pression présentant une lèvre d'étanchéité flexible qui entre en contact avec le siège arrière avant d'assurer un contact entre un épaulement de tige et le siège arrière, l'épaulement de tige étant positionné au-dessus de la lèvre flexible, le mouvement de la tige étant ainsi limité tout en permettant à la pression de soupape intérieure d'assurer une étanchéité entre la lèvre flexible et le bonnet.
