    摘要: In an expanding gate valve, tangential pins (70) are received loosely in peripheral grooves (62) of floating valve seats (26) to prevent the seats from moving inwardly far enough to drag against a gate mechanism (32) which is collapsed for movement between open and closed positions of the valve. Alternative arrangements provide retainer rings (122, 130) which engage shoulders (128) of the seats to limit their inward floating movement.
