This year, Val-Matic Valve & Manufacturing Corp. celebrates a remarkable milestone: 60 years of innovation and leadership in the water, wastewater, industrial, and building markets . Since its founding in 1966 with a single product—the Silent Check Valve—the company has grown into North America’s leading supplier of air valves and a premier manufacturer of engineered flow control solutions . This post explores Val-Matic’s rich history, their comprehensive product lines, and how their technologies solve critical challenges in infrastructure and industry worldwide.

The Val-Matic Story: A Legacy of Innovation Since 1966

Val-Matic was founded in 1966 in Elmhurst, Illinois, by Andrew Nuter and Ted Makowan, who were the company’s sole employees for the first year . Their first product, the Silent Check Valve, established a foundation of quality and innovation that would guide the company for decades .

Within a year, work began on what would become Val-Matic’s signature product line: Air Valves. Today, the company manufactures nine types of air valves and holds the distinction of being the leading supplier of air valves in North America . This expertise in managing air in pipelines has made them an indispensable partner for engineers designing water transmission systems, treatment plants, and sewage forcemains .

The company’s growth has been marked by continuous expansion and product development :

Today, the company operates from 178,000 square feet of manufacturing and office space across two Illinois facilities, equipped with advanced welding, machining, and testing capabilities to produce valves that meet American Iron and Steel (AIS) and Buy America requirements .

Comprehensive Valve Solutions for Critical Applications

While Val-Matic does not manufacture traditional soft rubber duckbill valves, they offer several product lines that serve similar functions in backflow prevention and flow control, with proven performance in demanding applications.

Swing-Flex® Check Valves: The Durable Alternative

The Swing-Flex® Check Valve, introduced in 1986, represents Val-Matic’s answer to applications requiring reliable check valve performance in harsh conditions . Unlike traditional duckbill valves which use a flexible rubber sleeve, the Swing-Flex® features a one-piece steel and nylon reinforced Buna-N rubber disc that provides exceptional durability .

A documented case study from a 220-MW power station’s bottom ash recovery system demonstrates the Swing-Flex®’s superiority. The facility’s original duckbill check valves failed in as little as two weeks due to abrasion from the aggressive bottom ash media. Ball check valves failed within four months, and conventional swing check valves required replacement every six to twelve months .

In October 1987, plant engineers installed a Val-Matic Swing-Flex® Check Valve. After five years of continuous service with no maintenance, Val-Matic had the valve removed and tested. Independent testing by Pittsburgh Testing Laboratories confirmed the valve seating was “drop tight with no leakage observed” at 55 psi, with only two drops observed during a five-minute 200 psi test . This real-world performance demonstrates why Val-Matic valves are trusted in the most severe applications.

FloodSafe® Inflow Preventer

Introduced in 2005, the FloodSafe® Inflow Preventer was developed in response to customer inquiries and represents the first product of its kind . It is designed to prevent the entry of contaminated water or other fluids from entering the air valve outlet and subsequently the pipeline . This innovative solution addresses a critical infrastructure vulnerability, protecting water quality and system integrity.
