Functional Description
The FY500 is a nozzle-reed system positioner with coil. Accepts a setpoint signal from a controller or other device through a twisted pair of wires.
After executing auto calibration procedure, it compares this input signal to the actual valve position, which it measures with the Hall Effect sensor that is connected to the feedback module.
The difference between the setpoint and the actual position is then amplified and a corrective current signal is sent to the I/P converter module .
The supply pressure to the FY500 passes through an internal pressure regulator that regulates it to approximately 22 psi. The air then goes through an orifice that restricts the flow and air consumption.
The I/P converts the current signal to a pneumatic signal, which is sent to the diaphragm module and the spool valve.
The spool valve directs supply air to the actuator to move the valve until the Hall Effect Sensor reading agrees with the setpoint.
