Flow Control Industries, a Washington State corporation, is the world's leading designer and manufacturer of industrial grade, pressure independent, modulating, flow control valves used in the HVAC industry.

Flow Control Industries' valves dramatically reduce the number of poor performance issues, capital expenses, and operating costs associated with unavoidable system pressure fluctuations. DeltaPValves® are designed to replace the conventional 2-way control valve and balancing valve pair installed at heating and cooling coils in buildings with a superior performing product.

Unlike conventional control valves, DeltaPValves don't hunt in response to unavoidable system pressure fluctuations because Flow Control Industries' patented flow regulation unit constantly adjusts for pressure fluctuations. This leads to better heat transfer at the coils, minimum flow, minimum pressure, and maximum delta T.

Industrial quality pressure independent control valves are a technological advancement that enables hydronic systems to attain optimal energy efficiency and maximum capacity. Flow Control Industries' valve technology is protected by 17 US patents. The market strength of DeltaPValves® is that regardless of whether the economy is bullish or bearish, customers are always concerned with being able to conserve energy resources, add system capability, and reduce total ownership cost associated with their facilities.
