SAFETY CONSIDERATIONS
SHOCK HAZARD:
Hazardous voltage levels are present in the actuator. Only qualified service
and installation personnel should install or adjust this device.
ALIGNMENT:
Insure that the actuator shaft is in line with the valve plug stem. Misalign-
ment could damage the actuator and driven device or cause injury to
installation personnel.
AVOID ACCIDENTAL STARTING:
When installing the actuator, insure that line power to the unit is shut off.
When power is applied, the actuator may immediately respond to the control
signal. Inadvertent motion could damage the actuator and driven device
or cause injury to installation personnel.
IMPORTANT
:
When machining the control enclosure, thoroughly clean any metal chips
or residue from the enclosure before applying power.
HYDRAULIC OIL:
The standard oil used in REXA actuators or drives is Castrol Syntec SAE
5W-50 motor oil. Oil for special applications such as food grade would
be noted on the serial plate. The introduction of other fluids may cause
damage to the unit.
SPRING UNDER TENSION:
REXA actuators, denoted by an E, R or U in the model number, contain a
spring under tension. Failure to properly remove this force before disas-
sembly can cause serious injury to maintenance personnel. Contact REXA
for disassembly instructions.
RELIEVING INTERNAL PRESSURE:
When the electric power is off (fail in place units) or the motor is not turn-
ing, hydraulic pressure remains locked within the cylinder. This internal
pressure must be relieved before disconnecting any hydraulic fitting. Open
the cylinder bypass (3/16” hex) located on the power module for fail in place
units or remove electric power to the solenoid on spring fail units. See
section 3.M2 of the Trouble Shooting and Repair Manual.

ACCUMULATOR FAILURE OPTION:
REXA actuators denoted by an A in the model number contain an accumulator
charged with high-pressure nitrogen. These actuators also have an automatic
recharging cycle for the accumulator. Failure to properly follow installation
instructions may cause serious injury to maintenance personnel and/or dam-
age to equipment.
NPT PLUG AND CONDUIT CONNECTIONS:
During assembly, Loctite 767 compound—or its equivalent—must be used
on threads of all NPT plug and conduit connections to ensure a watertight
seal.

INTRODUCTION
REXA Xpac actuators and drives are Electraulic (self-contained,
electro-hydraulic) devices. They are controlled by a dedicated micro-
processor located within the control enclosure and operated by a fluid
power system in the power module. Suitable for 100% duty cycle
service, the Xpac is ideal for any automatic control application.
The Xpac product line is offered in three different series. The R
Series are quarter turn actuators designed to operate rotary devices
(ball valves, butterfly valves, directly coupled louvers, etc.). The L
Series are designed for linear applications. The D Series of drives
are derived from the rotary actuator and designed to operate louvers
and dampers.
When ordering spare parts or requesting information on a specific
actuator, please have available the actuator serial number. This is
located on a stainless steel name tag attached to the actuator.
Units supplied to the provisions of Class I, Division 2, Groups B,
C & D or Class I, Division 1, Groups B, C & D require additional
installation procedures to comply with agency approvals. Refer
to Appendix D for details.
