Description

The flow through a globe valve follows a course that takes nearly two 90º changes in direction. But, because the seating of a globe valve is parallel to the line of flow of the liquid, it can be used to throttle the flow to any required degree or to give positive shut-offs. The economy and dependability of the Asahi/America globe valve make it desirable for many applications where this pressure drop is not critical. These valves are designed for manual operation only.
