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.
