ABSTRACT:
A flow control apparatus having a valve body forming a longitudinal axis with an inlet and an outlet connected by flow passage that are all substantially disposed on the longitudinal axis to provide a straight flow path is disclosed. A moveable flow control sleeve is concentrically disposed about a cylindrical seat member fixed in the valve body. Radially opposed ports are disposed in the seat member. A quick acting 90 degree rotatable stem is operably connected to the flow control sleeve to reciprocate the sleeve axially along the cylindrical seat to and from the open and closed position to regulate the fluid flowing through the opposed ports and valve apparatus. A flowmeter sensor is mounted with the valve body for providing a signal in response to the rate of flow through the flow passage. The signal is usable by a flow rate determining system which may be connected to a valve actuator for automatically operating the valve in response to certain prearranged flow conditions.
