Abstract
Response time to an actuating signal of an in-line valve including a sleeve (26) closeable against the seat (24) by reciprocal movement within a body (10) on a guide (44) is minimized by providing an actuating chamber (86) bounded by the complementary, mating surfaces (82, 84) so that less pressurizing fluid need be introduced into the chamber (86) to cause actuation. Response time is further enhanced by making the guide (44) in the form of a tube which vents the interface between an annular wall (62) and a web (30) on the sleeve (26) against which pressure in the chamber (86) acts.
