Article: The New DeltaP SmartValve: Using Real-Time Data to Guarantee Performance
In the quest for more efficient systems and reduced maintenance, the missing piece has always been the lack of accurate real-time operating data of the hydronic system. The DeltaP SmartValve has been designed as a direct remedy for this problem.
Whitepaper: Defining Pressure Independence – Accuracy
Despite the industry moving toward pressure independent control valves, an agreed upon definition of pressure independence has not been established. As the inventors of pressure independent technology and industry leaders in performance, precision control and durability, Flow Control Industries has defined pressure independence as maximum of ±5% allowable deviation of total flow from setpoint. While nearly all other manufacturers of “pressure independent” valves claim to meet or exceed this specification, third party testing data clearly shows that the DeltaPValve is the only one to perform as advertised.
Whitepaper: Pumping Configurations and DeltaPValve® Savings
Pump energy can be a large cost for chilled water systems. System configurations have evolved over the years in an attempt to save energy and increase performance. In this paper several different system configurations were modeled to predict the electrical cost and savings comparison of chilled water pumps. Additionally, typical control valves are compared to pressure independent DeltaPValves that are proven to increase delta T, decrease flow, and decrease pumping demands.
Whitepaper: The DeltaPValve® System – Standard Control Gets Substandard Performance
HVAC system designers and operators have a new system technology that increases efficiency and the effective system capacity, cures low Delta T syndrome, improves comfort and simplifies operation. A DeltaPValve® System, using DeltaPValves as manufactured by Flow Control Industries, is revolutionary, changing the way HVAC systems are designed and operated. By establishing unprecedented system stability, the benefits of precision control extend throughout the HVAC system resulting in substantial energy savings as high as 40%. Precise control of an HVAC system provides efficient comfort for building occupants.
Whitepaper: The DeltaPValve® System – Instability First Order Losses – Fan Hunting
In "The DeltaPValve® System – Standard Control Gets Substandard Performance" the reader was introduced to the overall effects of standard control – wide coil LAT tolerance and instability - and how they can be mitigated using the precision control afforded by the use of the DeltaPValve ® System. In this paper, a portion of the topics raised in the previous paper will be explored in greater depth. Specifically, the first order ramifications of unstable coil LAT will be detailed.

Mobile App

DeltaPValve iOS App
Flow Wheel app for iPhone, iPad, and iPod touch. This app automatically calculates pipe size, capacity in tons, and Delta T for your cooling system. This app is perfect for engineers, sales reps, designers and plant managers.

Additonal Resources

System Integration and Delta T Validation
DeltaPValve® System Integration is intended to ensure correct physical installation and proper operation of every DeltaPValve®, delivering the required performance at each associated cooling or heating coil.
Manometer Sales
The three P/T ports on all DeltaPValves are an easily accessible feature to quickly confirm pressure independence and valve operation, or diagnose flow concerns. A handheld manometer is a basic tool that every installer, inspector or maintenance manager should have available during integration to manually check pressure readings to verify performance and sensor accuracy. While there are a number of manufacturers that provide acceptable manometers, Flow Control Industries typically utilizes the Dwyer model 490-4 for Wet/Wet 0-100 PSID service. FCI will be happy to assist in selecting and ordering new manometers.
About Flow Control Industries

Flow Control Industries, Inc. (FCI) is a specialty manufacturer of high-performance pressure independent control valves, delivering energy efficient products and services through a consultative process to increase building value and lower total cost of ownership.

The DeltaPValve®, FCI’s flagship product, was developed by Founder and Chairman Paul Skoglund, P.E. over 20 years ago when he realized that more effective valves could revolutionize mechanical system efficiency. As an industry pioneer, Paul was the first to create the patented design, development and application of pressure independent control valves.

FlowEnergy, provides a holistic energy intelligence and optimization solution that combines FCI’s proven hardware, advanced software and expert guidance to deliver unprecedented control, in-depth insights, and sustainable savings.
