A valve body defines a fluid passage and a valve sealing body is positioned there. The valve sealing body is operable between open and closed positions which allow for fluid-flow and non-flow, respectively. The valve stem has a free end and an engagement end where the engagement end engages the valve sealing body so that rotation of the valve stem operates the valve sealing body between the open and closed positions. A measurement passage is defined through the valve stem from the free end to the engagement end. The measurement passage is in fluid communication with the fluid passage when the valve sealing body is in the open position, and at least one sealing member is positioned within the measurement passage.

Port integrated within valve stem

A valve assembly is disclosed. The valve assembly includes a valve body having an inlet opening, an outlet opening, and a flow passage extending therebetween. A check valve is disposed within the flow passage. A shutoff valve is disposed within the flow passage. A venturi is disposed within the flow passage between the check valve and the shutoff valve. A fluid system into which the valve assembly is installed is also disclosed.

Combination valve

A fluid flow switch sensing device includes a switch, a pivotally disposed bracket assembly which activates the switch to a desired switch function, and a paddle assembly for causing pivotal movement of the bracket assembly in response to fluid flow in a conduit. A button assembly, cooperatively associated with the bracket assembly, is provided for external manual actuation and deactuation of the fluid flow switch sensing device.
