Abstract
There is provided a valve comprising a housing and a closure member. The housing includes a seat, a flow receiving communicator for receiving fluid flow, a flow discharging communicator for discharging the received fluid flow, and an inner surface that defines a housing cavity. The closure member is moveable within the housing cavity relative to the seat. The closure member includes at least one groove. For each one of the at least one groove, independently, a value of a depth of the groove, taken along a longitudinal cross-section of the closure member, is at least 50% of a value of a maximum radial distance, of the closure member within the cross-section, measured from a central longitudinal axis, of the closure member, to the outermost surface of the closure member.

A valve comprising:
- a housing, including:
- a seat;
- a flow receiving communicator for receiving fluid flow;
- a flow discharging communicator for discharging the received fluid flow;
- and
- an inner surface that defines a housing cavity;
- and
- a closure member, moveable within the housing cavity relative to the seat;
- wherein:
- a flow-conducting passage is defined within the housing cavity, between the inner surface and the closure member;
- the housing and the closure member are co-operably configurable, while the valve is emplaced such that the central longitudinal axis, of the housing cavity, is emplaced, relative to a horizontal plane, within a range of orientations, wherein the range of orientations is from an emplacement of the central longitudinal axis within a horizontal plane to an emplacement of the central longitudinal axis at an acute angle of less than 30 degrees relative to the horizontal plane, in a closed condition and in an open condition, wherein:
- in the closed condition, the closure member is seated on the seat such that the flow receiving communicator is occluded;
- and
- in the open condition, the closure member is spaced apart from the seat, such that there is an absence of occlusion of the flow-receiving communicator by the closure member;
- the housing and the closure member are co-operatively configured, such that while:
- (i) the valve is emplaced such that the central longitudinal axis, of the housing cavity, is emplaced, relative to a horizontal plane, within a range of orientations, wherein the range of orientations is from an emplacement of the central longitudinal axis within a horizontal plane to an emplacement of the central longitudinal axis at an acute angle of less than 30 degrees relative to the horizontal plane, (ii) the housing and the closure member are co-operating to establish the open condition, wherein the spacing apart of the closure member, relative to the seat, is such that the closure member is traversed by a longitudinal cross-section of the housing cavity, and (iii) while a fluid flow is being received by the flow receiving communicator:
- the received fluid flow is conducted from the flow receiving communicator, via the flow-conducting passage, to the flow discharging communicator;
- and
- while being conducted via the flow-conducting passage, the received fluid flow is conducted via a flow-conducting space of the flow-conducting passage, wherein the flow-conducting space defines a cross-sectional flow area, of the flow-conducting passage, defined within the longitudinal cross-section of the housing cavity;
- a value of a minimum radial distance of the housing cavity, defined within the longitudinal cross-section of the housing cavity, and measured from a central longitudinal axis, of the housing cavity to the inner surface of the housing, exceeds a value of a maximum radial distance of the closure member, defined within the longitudinal cross-section of the housing cavity, and measured from a central longitudinal axis of the closure member, to an outermost surface of the closure member, by a value that is greater than, or equal to, 5/1000 inch, and that is less than, or equal to, 15/1000 inch;
- and
- a ratio, of a value of the cross-sectional flow area, defined within the longitudinal cross-section of the housing cavity, to a value of a cross-sectional area, within the longitudinal cross-section of the housing cavity, is at least 0.5.
