    摘要: The present invention relates to an on-off valve provided with sealing means for the control stem. The sealing means comprise a plurality of sealing rings of expanded graphite and a gland device for placing said rings in compression. The sealing means further comprise a further active element (20) arranged on the bottom wall (30), provided with an expansion room (22) wherein the fluid pressure causes a thrust action towards said sealing ring. Said sealing means distribute the strain state of the compressed rings in an optimum manner.
