Fisher™ 3570 pneumatic valve positioners are used with control valve assemblies to provide an accurate valve stem position that is proportional to the input signal received from a control device. These positioners are normally used with pneumatic piston actuators. However, product types within the 3570 family can be used with pneumatic, long-stroke, cylinder, or pneumatic diaphragm actuators.
