CONTROLLER APPARATUS, SYSTEM AND/OR METHOD FOR CONTROLLING PRESSURES IN A FLUID CONTROL SYSTEM

摘要

A fluid control system has a body with the inlet passage in fluid communication with a discharge passage. The position of a choke piston in the body controls flow of the fluid from the inlet passage to the discharge passage. A controller connected to the body has an actuator connected to a linkage that is connected to the choke piston. The controller positions the choke piston in the body using the actuator and the linkage to control the flow of a fluid from the inlet passage to the outlet passage.
