PROCESS FLUID ACTUATED PILOT OPERATED CONTROL VALVE |
摘要 |
A flow control system includes a pilot driven valve having a pilot assembly and a main valve assembly; a displacement measurement component coupled to the main valve assembly indicating displacement of the main valve assembly; and a proportional solenoid responsive to a signal from the displacement measurement component that displaces the pilot assembly in proportion to the changes in displacement of the main valve assembly. The valve is controlled by sensing a displacement of the main valve assembly; and modulating the proportional solenoid in response to the displacement of the main valve assembly. |
