9. 2 Principle of Operation 685 piston actuators utilize a pneumatically controlled piston that moves inside of a cylinder to generate thrust A seal contained on the circumference of the piston provides a seal between the piston and the cylinder preventing supply pressure leakage From an equilibrium state the actuator operates by reacting to a force unbalance that is created by increasing supply pressure on one side of the piston and decreasing it on the other This moves the piston up or down and results in a repositioning of the attached control valve Travel can be adjusted using travel limits within a valve positioner which limit the travel range of the actuator The optional handwheel manual override does not have the ability to act as a hard travel stop An optional handwheel manual override is capable of extending or retracting the actuator manually and can be engaged at any position from full open to full close This override utilizes a worm gear assembly that is attached to the stem connector and not attached to the cylinder or piston rod This enables the manual override to reposition the control valve even if the Product Bulletin 61 2 685 September 2014 actuator cylinder or piston is removed for maintenance Instrument Selection An excellent selection of sensitive and accurate instruments is available for 685 piston actuators These include the FIELDVUE DVC6200 digital valve controller as well trip valves an
