Introduction

Scope of Manual

This instruction manual provides installation, operation, maintenance, and parts information for the Fisher VBL

volume booster (figure 1). Refer to separate instruction manuals for information regarding the valve body, actuator,

and other accessories.

Do not install, operate, or maintain a VBL volume booster without being fully trained and qualified in valve, actuator

and accessory installation, operation and maintenance. To avoid personal injury or property damage it is important to

carefully read, understand, and follow all of the contents of this manual, including all safety cautions and warnings. If

you have any questions about these instructions, contact your Emerson Process Management sales office before

proceeding.

Description

The VBL volume booster is used in conjunction with a positioner on a throttling control valve to increase stroking

speed. The booster has a fixed deadband (controlled by the seat‐to‐seat dimension of the supply and exhaust plugs)

which is factory set during assembly and testing. In addition, the booster incorporates soft‐seat construction and an

integral bypass restriction to eliminate positioner saturation problems that can occur with volume boosters that do

not have these features. Adjustment of the integral bypass restriction is necessary for system stability. This adjustment

does not affect the deadband of the booster, but does permit the control valve to respond to small input signal

changes from the positioner without sacrificing steady‐state accuracy.
