Abstract

A pressure control apparatus includes a main line section and a branch line operably joined to and extending from the main line section. A housing around the branch line has a first wall and a second wall opposed to the first wall, and a first opening is in the first wall. A plug is operably positioned in the branch line, and the plug has a first position that prevents fluid flow through the branch line and a second position that permits fluid flow through the branch line. A loop extends from the plug, and a lever pivotally connected to the second wall and extending through the loop and the first opening in the first wall positions the plug to the first and second positions.
