Unival® BUTTERFLY VALVES
MULTIVOLTAGE ELECTRIC ACTUATOR - MAIN ACCESORIES
Data Sheets Manual
DIGITAL POSITIONNER
The DPS 2005 is a device for the J3 electric actuator that turns the actuator
in a valve positioner servo controled.
The DPS 2005 is a modulus with a microprocessor (CPU) which manages
digitally the analogical input and output and compare them with the position
of the actuator to stablish an uniform relation.
The analogical inputs are sent to CPU where they are processed for his
continous comparison with the position of the actuator, this allows to obtain
a very high sensitivity next to a very high repetitivity of the position (see
characteristics).
The DPS 2005 in communication with the electronic system of the actuator
provides an integral management of the motion on the actuator.
The DPS 2005 is available for the ”H” and “L” series.

SAFETY BLOCK SYSTEM
The BSR safety blok system is an automatism that when couple to the
L & H Series multivoltage electric actuators lets the valve situate in a
prefereable position NC or NA when there is a power supply failure.
Inside of the housing actuator there are BSR’s print circuit board and the
battery pack which are kept in continuous charge.
In case of the valve is not in the prefereable position and there is the
power supply cut, the BSR system returns the valve back to the prefereable
position by means of the batteries tension operating as a “single
acting” actuator.
