Elbow globe valve
A globe valve assembly can include a globe valve that can include a valve stem that defines a valve stem axis, a valve seat, a plug secured at a distal end of the valve stem, and a valve body that supports the valve seat. The valve body can define an inlet passage that extends between an inlet opening and the valve seat and an outlet passage that extends between an outlet opening and the valve seat.
1 . A globe valve assembly comprising:
a globe valve that includes:
a valve stem that defines a valve stem axis;
a valve seat;
a plug secured at a distal end of the valve stem to be moved relative to the valve seat by movement of the valve stem to control flow across the valve seat; and
a valve body that supports the valve seat, the valve body defining an inlet passage that extends between an inlet opening and the valve seat and an outlet passage that extends between an outlet opening and the valve seat;
wherein the inlet opening defines an inlet flow orientation and the outlet opening defines an outlet flow orientation; and
wherein, as projected onto a reference plane that is perpendicular to the valve stem axis, the inlet flow orientation extends at an oblique angle relative to the outlet flow orientation.
2 . The globe valve assembly of claim 1 , wherein the inlet flow orientation and the outlet flow orientation are substantially parallel to the reference plane.
3 . The globe valve assembly of claim 2 , wherein the inlet flow orientation and the outlet flow orientation are aligned along the reference plane.
4 . The globe valve assembly of claim 3 , further comprising:
a bonnet secured to a top of the valve body, the bonnet including a stem passage to guide movement of the valve stem and at least one packing set arranged within the stem passage.
5 . The globe valve assembly of claim 1 , wherein the globe valve is secured to an inlet flow conduit at the inlet opening and is secured to an outlet flow conduit at the outlet opening, so that the plug is arranged to control flow from the inlet flow conduit to the outlet flow conduit via the globe valve; and
wherein the valve stem axis is substantially vertical.
6 . The globe valve assembly of claim 5 , wherein one or more of the inlet flow orientation or the outlet flow orientation are substantially horizontal.
7 . The globe valve assembly of claim 6 , wherein the inlet flow orientation and the outlet flow orientation are substantially horizontal.
8 . The globe valve assembly of claim 1 , wherein the valve body is an integrally formed body.
9 . The globe valve assembly of claim 1 , wherein the valve body is an additively formed body.
10 . The globe valve assembly of claim 1 , wherein the valve body includes an upper body portion and a lower body portion configured to be selectively secured together at any of a plurality of relative angular orientations to define the oblique angle between the inlet flow orientation and the outlet flow orientation.
11 . A method of forming a globe valve assembly, the method comprising:
forming a valve body to support a valve seat, wherein the valve body defines: an inlet opening, an outlet opening, a seat passage for flow across the valve seat, an inlet passage that extends between the inlet opening and the seat passage, and an outlet passage that extends between the outlet opening and the seat passage;
positioning a valve stem within the valve body, the valve stem defining a valve stem axis; and
arranging the inlet passage at an oblique angle relative to the outlet passage when viewed from a reference plane extending perpendicular to the valve stem axis.
12 . The method of claim 11 , further comprising:
securing the valve stem to the valve body to control flow across the valve seat by moving a plug at a distal end of the valve stem relative to the valve seat.
13 . The method of claim 12 , wherein securing the valve stem to the valve body includes securing a bonnet to a top side of the valve body, the bonnet including a stem passage that receives the valve stem along the valve stem axis, and at least one packing set arranged around the valve stem within the stem passage.
14 . The method of claim 11 , wherein forming the valve body includes integrally forming the valve body.
15 . The method of claim 11 , wherein forming the valve body includes additively forming one or more body portions of the valve body.
16 . The method of claim 15 , wherein the one or more body portions include:
an upper body portion; and
a lower body portion; and
wherein the upper body portion is selectively rotatable relative to the lower body portion to any of a plurality of angular orientations to define a corresponding angular offset between an inlet connection of the valve body and an outlet connection of the valve body.
17 . A method of installing a globe valve assembly, the method comprising:
providing a globe valve that includes valve body that supports a valve seat, a valve stem movably secured to the valve body to define a valve stem axis, a plug secured at a distal end of the valve stem to be moved relative to the valve seat by movement of the valve stem to control flow across the valve seat, the valve body defining an inlet passage that extends between an inlet opening and the valve seat and an outlet passage that extends between an outlet opening and the valve seat;
aligning the inlet opening at an oblique angle relative to the outlet opening when viewed from a reference plane extending perpendicular to the valve stem axis; and
securing an inlet flow conduit at the inlet opening and an outlet flow conduit at the outlet opening.
18 . The method of claim 17 , wherein the globe valve further includes a bonnet secured to a top of the valve body, the bonnet including a vertical stem passage to guide movement of the valve stem and at least one packing set that surrounds the valve stem within the vertical stem passage.
