Guidelines for Usage

Large Volume Control Valve Actuators: Control valves that require
large volume actuators may require Model VB-250 volume
boosters to ensure adequate stroking speed� HPP-5 positioners
are NOT compatible with volume boosters� The HPP-4 positioner
must be used�
Bleed to Pressure System (BPS): The HPP-5 positioner is typically
used for applications where no discharge pressure of less than
350 psig is available� The very low steady state bleed of the
positioner makes it efficient for reducing atmospheric emissions�
The HPP-5 positioner is also compatible with the Becker BPS�
High Gain Systems: The HPP-5 positioner is not preferred for this
application� It may be successfully used with small diameter (4
inch and smaller) ball valves for this application, but its limited
orifice capacity makes it too slow for controlling larger valves�
CVE Globe Pattern Control Valves: The Becker HPP series position-
ers are compatible with globe style control valves, but require a
minimum of 2 inches of actuator stroke for proper feedback and
operation�
This makes it impossible to use this positioner with most globe
valves smaller than 4 inch port size�
Compatible Actuators:
Becker RPDA Actuators (Rotary Piston Double-Acting)
n
Becker LPDA Actuators (Linear Piston Double-Acting)
n
Other manufacturer's double-acting piston actuators*

*Consult GE for additional information
Retrofit Compatibility:
Excellent performance is achieved by pairing the HPP-5 positioner
with genuine GE control valve actuators� Should you already
have existing control valve actuator(s) in service, the addition of a
Model HPP-5 positioner can improve performance and eliminate
atmospheric bleed emissions if using the BPS (Bleed to Pressure
System) feature�

*Resolution and repeatability figures reflect a positioner that is adjusted with a
minimum deadband to reduce bleed gas� If the deadband is eliminated (slightly
increasing the bleed gas), resolution and repeatability will improve�
