The action can be changed by inverting the bellows assembly. This requires adjusting the bias spring to reset the starting point of piston travel. Legacy Support

The Fisher 3590 operates as a force-balance instrument. The electrical input signal is received by an I/P (current-to-pressure) transducer, which creates a proportional pneumatic signal. This signal acts upon a bellows or diaphragm assembly that moves a beam. As the beam pivots, it changes the relationship between a nozzle and a flapper, modulating the relay output pressure to the actuator. Feedback from the valve stem is provided through a range spring, ensuring the valve reaches the exact commanded position. Maintenance & Safety Guidelines Pressure Release:
