Abstract
An aspect includes a globe butterfly valve that includes a valve inlet, a valve outlet, a globe housing with a spherical body between the valve inlet and the valve outlet, and a globe butterfly valve disc operably disposed within the globe housing. The globe housing has a larger interior diameter than an inlet diameter of the valve inlet and an outlet diameter of the valve outlet. The globe butterfly valve disc is configured to block a flow path between the valve inlet and the valve outlet responsive to an outer edge of the globe butterfly valve disc being positioned proximate to an interior surface of the globe housing between the valve inlet and the valve outlet.

A dual valve system comprising:
- a valve body;
- a valve disc operably disposed within the valve body;
- a globe housing comprising a spherical body;
- a globe butterfly valve disc operably disposed within the globe housing;
- and
- a linkage system operably coupled to the valve disc and the globe butterfly valve disc, wherein the globe housing differs in geometry from the valve body such that opening of a first flow area between the valve disc and the valve body occurs prior to opening of a second flow area between to the globe butterfly valve disc and the globe housing responsive to movement of the linkage system.
A method of operating a dual valve system, the method comprising:
- driving a valve disc to rotate in a valve body using an actuator;
- and
- translating a rotational force of the actuator through a linkage system operably coupled to the valve disc and a globe butterfly valve disc, wherein the globe butterfly valve disc is disposed within a globe housing and the globe housing differs in geometry from the valve body such that opening of a first flow area between the valve disc and the valve body occurs prior to opening of a second flow area between to the globe butterfly valve disc and the globe housing responsive to the rotational force.
