NOTES
1. Adjustment and Installaon of VRG Controls equipment should be only
be performed by qualied personnel adequately trained and familiar with
products.
2. For technical assistance, please contact your local VRG Controls Sales
Representave or VRG Controls direct (www.vrgcontrols.com).
3. All values represent a starng point. Dynamic tuning with VPC in “live
control” will be necessary to opmize performance.
4. In this table, Pipeline Interconnects are dened >1.0 mile downstream
piping adjacent to control valve.
5. In this table, Close-Coupled System Applicaons are dened <1.0 mile
downstream piping adjacent to control valve.
6. Increasing number on the SUPPLY & EXHAUST ORIFICE will increase
the speed of response independently in each direcon (faster reset rate).
Refer to VPC Applicaon Schemac to determine which Adjustable Orice
controls OPEN and CLOSE speed.
7. Increasing number on the “D” TANK ORIFICE will introduces a DERIVATIVE
funcon controls the RATE of OUTPUT. Larger DERIVATIVE number of “D”
TANK Adjustable Orice introduces more dampening of the OUTPUT.
8. If stable control is achieved upon adjusng the VPC per the above
guidelines, the deadband may be reduced (smaller number on Sensivity
Adjusng Drum). For dynamic systems, do not reduce deadband to less
than “ZERO” as dened in Inial Adjustment Procedures.
9. If system is unstable upon adjusng VPC per above guidelines, correcve
adjustment to INCREASE CLOSING speed and REDUCE OPENING speed are
suggested. Addionally, the deadband may be increased (larger number on
Sensivity Adjusng Drum).
