Abstract

There is disclosed a unitized instrument manifold which creates a double block and bleed valving arrangement for use with a flow recording or measuring device. The bleed valve assembly permits venting of a first channel to the outside while in the open position yet does not interfere with the flow of fluid through the length of the first channel while the bleed valve assembly is in the closed position. The unitized manifold, including block and bleed valve chambers, may be cleaned by passing a narrow rigid rod through the channels of the manifold.
