Abstract

A three-way valve may be pressure balanced to improve efficiency of the three-way valve and to reduce operating forces and requirements for moving and/or manipulating plug assemblies within a three-way valve.

Claims (24)

1. A valve comprising:
a valve body;
three ports in the valve body;
an opening in a top of the valve body;
a second opening in a bottom of the valve body; and a pressure balanced plug assembly located, positioned, and orientated to control flow between the three ports.
2. The valve of claim 1, wherein the pressure balanced plug assembly is configured for linear actuation.
3. The valve of claim 1, further comprising a bonnet penetrating the valve body via the first opening.
4. The valve of claim 1, further comprising a second bonnet penetrating the valve body via the second opening.
5. The valve of claim 1, wherein the pressure balanced plug assembly includes an upper portion operably coupled to a plug head and a lower portion operably coupled to the plug head.
6. The valve of claim 5, wherein the pressure balanced plug assembly is configured to equalize pressure experienced by the upper portion, plug head, and lower portion.
7. The valve of claim 1, wherein the pressure balanced plug assembly is configured to achieve 70, 80, 90, and 95 percent total pressure balancing.
8. The valve of claim 1, wherein the pressure balanced plug assembly is configured to allow pressure equalization during actuation of the plug assembly.
9. The valve of claim 1, wherein one of the three ports is an inlet and the remaining two ports are outlets.
10. The valve of claim 1, wherein two of the three ports are inlets and the remaining port is an outlet.
11. A valve body comprising:
a cylindrical single piece valve body;
a first port and second port positioned inline with each other and distally located on opposing sides of the valve body;
a third port proximally located on a side differing from that of the first port and the second port.
12. The valve body of claim 1, further comprising an opening located in a proximal end of the valve body.
13. The valve body of claim 1, further comprising a second opening located in a distal end of the valve body.
14. A valve comprising:
a closure member including a longitudinal channel;
a first valve stem operably coupled to the closure member to effect movement of the closure member via movement of the first valve stem, the first valve stem including a first channel in communication with the longitudinal channel, the first valve stem including a first opening in communication with the first channel;
a first piston operably coupled to the first valve stem, such that movement of the first valve stem effects movement of the first piston, the first piston located between the first opening and the closure member;
a second valve stem operably coupled to the closure member to effect movement of the second valve stem via movement of the closure member, the second valve stem including a second channel in communication with the longitudinal channel, the second valve stem including a second opening in communication with the second channel; and a second piston operably coupled to the second valve stem, such that movement of the second valve stem effects movement of the second piston; the second piston located between the first opening and the closure member.
15. The valve of claim 14, wherein the closure member further includes a latitudinal channel in communication with the longitudinal channel.
16. The valve of claim 14, further comprising a valve body.
17. The valve of claim 16, further comprising a first bonnet operably coupled to the valve body, the first bonnet positioned, located, and configured to position the first valve stem.
18. The valve of claim 17, further comprising a first sleeve operably coupled to the first bonnet, an interior of the valve body, and the first piston, the first sleeve operable to allow movement of the first piston:
19. The valve of claim 18, wherein the first piston is configured to isolate a portion of an interior of the first sleeve from a remainder of the interior of the valve body.
20. The valve of claim 17, wherein the first piston is configured to isolate a portion of the first bonnet from a remainder of an interior of the valve body.
21. The valve of claim 17, further comprising a second bonnet operably coupled to the valve body, the second bonnet positioned, located, and configured to position the second valve stem.
22. The valve of claim 16, where in the second piston is configured to isolate a portion of an inner cavity of the valve body.
23. The valve of claim 14, further comprising a first plug stem operably coupling the first valve stem to the closure member, the first plug stem having an other channel in communication with the longitudinal channel and the first channel.
24. The valve of claim 14, wherein at least one of the first valve stem and the second valve stem is configured for attachment to a valve actuator.
