HPP-SB Positioner
Instruction Manual
Introduction
The
Becker HPP-SB series balanced seat de-
sign, single acting positioner represents a
breakthrough in valve control technology for the
natural gas industry. Built to exacting specifica-
tions, this easily maintained unit offers highly
accurate control characteristics over a wide
range of operating environments. The HPP-SB
eliminates atmospheric emissions when the
control valve is in a full closed standby position;
when it is in a full open monitor position; or
when it is controlling in a steady-state condi-
tion. Furthermore, the HPP-SB series positioner
is designed to allow bleed gas to be routed to a
lower pressure system, or downstream, for
complete elimination of bleed gas. The elimina-
tion of this expensive bleed gas ultimately
saves a significant amount of money for the op-
erating company and reduces the environ-
mental impact of atmospheric hydrocarbons
and diminishing natural resources.
Description
The Becker HPP-SB positioner is used to pro-
vide extremely accurate pressure control in con-
trol valve assemblies utilizing a controller or I/P
transducer and single-acting actuator. The
HPP-SB is designed for use with ball valves
16”* in diameter or smaller (when used with
Becker single-acting control valves).
*Valves over 16” in diameter require the use of
volume boosters.
