Pneumatic Actuator Applicability
Curve 1 and 2 indicate the minimum actuator pressure to open or close double acting actuator against system pressure.
To prolong valve life, actuators should be operated at minimum air actuator pressures.
Curves shown are based on packing bolt factory adjustment.
Packing bolt adjustment may be required to maintain the valve leak-tight.
If the packing bolt is over-tightened, the actuating pressure can not overcome the friction force between the over-tightened packing
and the stem. If the packing bolt is under-tightened for low system pressures, it may leak at high system pressures.
However, packing bolt torque must be sufficiently maintained to prevent packing from leakage.
V16A series with Double Acting Actuator -AD
To order valves with a pneumatic double acting actuator, insert the desired
actuator designator from the chart in the valve ordering number.

Safe Valve Selection
The selection of a valve for any application or systemdesignmust be considered to ensure safe performance.
Valve function, valve rating,material compatibility, proper installation, operationandmaintenance remain the sole responsibility of the system
designer and the user. DK-Lok accepts no liability for any improper selection, installation, operation or maintenance.
V16 series Pneumatic actuators are designed to actuate valves remotely. V16A and V16B series are available to be equipped with
pneumatic actuators in double acting.
