HPP-4 Positioner 
Instruction Manual

 

Introduction

 

 

The

 Becker HPP-5

 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-5

 series 

positioner is designed such that upon 
reaching a valve position and achieving 
a steady state, the gas consumption is 
very low.  Additionally, its bleed gas 
can be routed to a lower pressure 
downstream or fuel gas system, elimi-
nating bleed gas completely. This 
means significant savings to your com-
pany in terms of minimizing expensive 
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-5

 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-5 

can be 

used with various valve types that utilize 
a double acting pneumatic piston ac-
tuator.   The 

HPP-5 

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 a 

Becker HPP-4

 positioner with 

Volume boosters.
