Abstract

In a pilot-type pressure reducing valve wherein both the main and pilot valves (5, 11 Fig. 1) are associated with a plunger structure comprising a movable inner and a stationary outer member, at least one of the inner members includes a seal formed by at least two axially-spaced split annular sealing members 8 or 19 of fluorine resin.
