ABSTRACT:
A plug valve is provided with primary, secondary and tertiary seals. The primary seal includes an apertured sleeve which envelopes a plug portion of a valving member. The secondary and tertiary seals are provided by a delta ring and a lip of a diaphragm respectfully. The diaphragm is formed with a hollow annular groove proximal to the stem portion of the valving member. The delta ring is placed in this hollow annular groove with an interference fit to form a secondary seal between itself and the valving member and to augment the tertiary seal formed between a lip of the diaphragm and the valving member.
