Abstract:
A valve assembly for regulating a fluid flow, the valve assembly comprising:a body having a passage extending between a first port and a second port; a seat defining a portion of the passage; a member movable with respect to the seat, the member moving generally along an axis between a first configuration prohibiting fluid flow through the seat and a second configuration permitting fluid flow through the seat, the member including: a first portion adapted to sealingly engage the seat in the first configuration; and a second portion extending along the axis between a first section that is distal from the first portion and a second section that is proximate to the first portion; an actuator moving the member from the first configuration to the second configuration, the actuator defining an aperture extending along the axis and generally receiving the second portion, the aperture being defined by: a first segment generally guiding movement of the first section; and a second segment generally guiding movement of the second section; and a damper movable with respect to the actuator and located at a radial gap between the member and the actuator, the damper and the first portion being contiguously engaged and being defined by a single homogeneous part.
