700 FC Series Valve positioners converts a controller output (usually 3 to 15 psig or 4 to 20m ADC) to LinearlyRotary proportional TravelRotation & Pneumatic outputs. The Valve positioners are based on a force balance design for control applications that requires a high degree of reliability & repeatability at an economical cost. Optional NEMA 4X (IP65IPG6)-explosion proof versions allows for splashdownexplosive atmosphere and outdoor installation.
