Flow Control is a team of engineers and problem-solvers. We are in the business of changing people’s minds about HVAC systems. 

For the past 30 years, Flow Control has manufactured the DeltaPValve®, a pressure-independent control valve for the heating and cooling of commercial buildings. What sets the DeltaPValve® apart from other PICVs on the market is the scientific proof to confidently guarantee system stability, diversity and performance at an unparalleled level of accuracy. Your heating a cooling system is just that, a system, and when all of the components are implemented properly, you can gain upwards of 30% lost system capacity and guarantee consistent, year-round peak performance and efficiency. The DeltaPValve®’s unique and patented design has helped save Flow Control clients millions of dollars in annual energy savings, reduced operating costs and avoided capital costs.

The bottom line is that you don’t need to add more plants or build more capacity into your designs; you just need better control over your system. Our approach to creating a DeltaPValve® System gives you that control. We can help you ensure that:

•	Your system performs in real life the way you intended in its design
•	Each system component operates at its peak efficiency – all the time
•	You reliably realize full system capacity and reclaim lost capacity
•	Your designs reduce energy costs for an overall lower TCO
•	You contribute to a more sustainable energy solution

We support the design, installation and operation of systems built on experience, sound engineering fundamentals and industry best practices. We are scientists, environmentalists and industry veterans - and we love what we do. We couldn’t be more excited to support a passionate community around this product and work with our peers to build a better, more efficient and sustainable tomorrow.
