APPLICATIONS
 Eliminate Need for “PID” ControllersThe VRG Valve Pilot Controller (VPC) represents a major technological advancement compared to previous pilot type controllers. A VPC “ID” Series controller achieved superior performance at this power plant as compared with “PID” type controller that it replaced. |  Performance on Power Plant Trim RunsVRG Valve Pilot Controllers replaced Type 4195 controllers on power plant trim control valves. VPC’s significantly improved control accuracy and eliminated constant emissions. |  Prepackaged Solutions AvailableA Minnesota gas utility installed CABINET mounted VRG Valve Pilot Controllers. The system provides excellent control accuracy, and reduced emissions in tandem with new Type 1061 actuators and ball type control valves. |

 Remote Control Options AvailableCABINET mounted VPC Valve Pilot controllers are shown with ESC “remote setpoint control” via a 4-20 mA command signal. This gas utility experienced trouble free operation through harsh Minnesota winter without application of instrument heat. |  VRG Resists CorrosionFlorida based gas pipeline replaced existing Type 624 controllers, 3570 positioners and MCV devices with VRG components. VRG designs feature much greater corrosion resistance in marine environments without a premium price. |  Improve Control at Power PlantsExisting Fisher globe control valves were retrofit to replace Type 4195 pressure controllers at Florida power plant. VPC’s improved control accuracy from ± 7 psig to better than ±1.0 psig and simplified adjustment. |
 New Generation Pilot ControlGas Pipeline customer replaced existing Becker pilot controllers with VRG’s Valve Pilot Control System. The retrofit was simple and easy with improved corrosion resistance. The VPC’s improved sensitivity ensures monitors remain non-venting even when pipeline operating pressure is pushed to the max. |  Improved Design Over “PID” PilotsA Texas power plant replaced VRP “PID” Type due to corrosion issues. VPC design provided corrosion resistance, simplified adjustment and greatly improved control accuracy and speed of response. |
