3INSTALLATION
3.1 General
1. Check to see that the desired failure mode is correct
(Figures 1 & 2).In the spring-to-close mode,the actuator
will cycle clockwise to close upon loss of pressure. If the
spring-return actuator is not set up in the configuration
desired, follow the disassembly procedure section 4.2.
Reverse the orientation of the pistons, then reassemble
following the assembly procedure, section 4.3.
2. Mount the actuator to the valve, following the direction
in the linkage AMI or valve IMO.
3. Connect a regulated air supply to the NPT fitting in the
actuator housing. CAUTION: The maximum operat-
ing pressure is 116 psi (8 bar).
4. Adjust the stop screws following ASSEMBLY Section
4.3.5. Stops can be adjusted by up to ±4 degrees.
3.2 Operation
1. The actuator series, size, operating pressure, output
torque,spring directions,and drive type is determined by
the actuator designation.
2. The label lists the actuator series, size, operating pres-
sure, maximum pressure, and serial number. Actuator
designation example, VPVL300 SR6 B F07-N-L-19, is a
spring-return series, VPVL300 double-opposed piston
actuator that has 80-psi (5.5-bar) springs, a Teflon®-
coated anodized housing (protection B), an end-of-
stroke output torque of 41.1 FT•LBS (55.7 N•m),mounts
via an F07 pattern, and uses a 19-mm female parallel
square to drive the valve.
4MAINTENANCE
4.1 General
NOTE: All VPVL actuator fasteners are metric. Under normal
operating conditions the actuator requires only periodic
observation to ensure proper adjustment. Service kits are
available to replace seals and bearings (soft parts). These
parts are identified in (Figure 23) and listed in (Table 3).
(Table 1) below lists kit part numbers.
4.2 Disassembly
When disassembly of the actuator is required for maintenance,
remove the actuator from the valve. Ensure proper lifting
procedures are followed when moving or carrying actuators.
CAUTION: Do not use the M5 VDE/ VDI mounting holes
or the M6 hole in the pinion for lifting the actuator.
When disassembling VPVL actuators, use caution and be
certain that the actuator is free from accessories and the
air supply is disconnected. When the actuator is a spring-
return unit, make sure that the actuator is in the failed
position before disassembling.

To limit the rotation on the stroke beyond the standard ±4˚ of
a VPVL actuator, a stainless steel 100% adjustable travel
stop option can be added.The stops,located in the end caps,
allow the valve position to be set anywhere between full
closed and full open. This option limits travel of only the
couter-clockwise stroke for standard double-acting and
spring-closed units.
Follow the proceeding steps in order to set the 100%
adjustable travel stops.
