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.

An aspect includes a dual valve system that includes a first valve body and a first valve disc operably disposed within the first valve body, where the first valve disc has a first disc geometry. The dual valve system also includes a second valve body and a second valve disc operably disposed within the second valve body, where the second valve disc has a second disc geometry. The dual valve system further includes a mechanical linkage operably coupled to the first valve disc and the second valve disc, where the second disc geometry differs from the first disc geometry such that opening of a first flow area between the first valve body and the first valve disc occurs prior to opening of a second flow area between the second valve body and the second valve disc responsive to movement of the mechanical linkage.

Dual valve system with mechanical linkage

An aspect includes an offset parallel valve system that includes a first valve body and a first valve disc operably disposed within the first valve body. The offset parallel valve system also includes a second valve body in parallel with the first valve body and a second valve disc operably disposed within the second valve body, where the second valve disc is laterally offset from the first valve disc. A linkage system is operably coupled to the first valve disc and the second valve disc. The linkage system includes an armature coupled to a grooved linkage member having a first groove and a second groove. The first groove delays movement of the second valve disc as the first valve disc rotates, and the second groove controls a rotation angle of the second valve disc.
