초록

An automatic control valve has a main valve member moveable between open and closed positions thereof in response to pressure applied to a first piston or diaphragm in a first control chamber. The valve member moves to modulate flow through the valve to maintain desired flow conditions. Pilot pressure signals are generated to reflect the flow conditions, usually upstream and downstream from the valve, which signals are processed to generate a control signal which is fed to the first control chamber to control pressure therein. Normal movement of the valv...

청구항

An automatic control valve comprising: (a) a valve body having an inlet port, an outlet port, and a valve seat disposed between the ports, the valve seat defining a valve opening to permit communication between the ports, (b) a main valve member moveable between a closed position against the seat to close the valve, and an open position spaced from the seat to control flow of liquid through the valve opening to maintain a desired flow condition through the valve, (c) a first partition means moveable between extended and retracted positions thereof to ref...
