HPP-4 Positioner
Instruction Manual
Introduction
The
Becker HPP-4
series positioner
represents a breakthrough in valve con-
trol technology for the natural gas in-
dustry. Built to exacting specifications,
the easily maintained unit offers highly
accurate control with excellent control
characteristics in a broad range of oper-
ating environments. The
HPP-4
series
positioner is designed such that its
bleed gas can be routed to a lower
pressure downstream or fuel gas sys-
tem, eliminating bleed gas completely.
This means significant savings to your
company in terms of minimizing expen-
sive bleed gas as well as a cost saving
means of minimizing the environmental
impact of atmospheric hydrocarbons
and diminishing natural resources.
Description
The
Becker HPP-4
positioner is used in
control valve assemblies with a control-
ler or I/P transducer and double acting
actuator to provide accurate flow or
pressure control. The
HPP-4
can be
used with various valve types that utilize
a double acting pneumatic piston ac-
tuator. The
HPP-4
design positioner
represents Becker’s commitment to
continuos development of new products
and updating of existing products to
maximize their performance while re-
taining simple operation and minimum
maintenance.
Valves over 16” in diameter require the
use of
Becker VB-250
Volume boost-
ers.
