Abstract

A pressure equalization valve for alternatingly equalizing pressures between a first fluid source and at least two second fluid sources is disclosed. The pressure equalization valve includes a valve body, which includes a first port in fluid communication with the first fluid source and at least two second ports in fluid communication with the at least two second fluid sources, respectively, and a valve gate movable between a first equalizing position, wherein the valve gate allows fluid flow through one of the second ports and restrains fluid flow through another of the second parts to equalize substantially the fluid pressure between the first fluid source and one of the second fluid sources, and a second equalizing position, wherein the valve gate restrains fluid flow through the one of the second ports and allows fluid flow through the other of the second ports to equalize substantially the fluid pressure between the first fluid source and another of the second fluid sources. The valve further includes a chamber in the valve body between the first part and the second ports, wherein, as measured in planes perpendicular to the central axis of the first port, a largest cross sectional area of the chamber is at least 10 times larger the smallest cross sectional area of the first port.
