Griswold Controls

David Griswold's legacy lives on through the strong foundation he built for our company. His spirit will continue to be the spark of passion and inspiration for innovation. The story of Griswold Controls begins long before the company's inception on October 16, 1960 and continues to drive our true north to this day. Before age 5, David Griswold watched and helped his father develop hydraulic products. David and his brother would leave the lawn sprinklers running too often and long so David's dad developed the first diaphragm valve (Clayton Valves) and timer control which became the first automated lawn irrigation system.

Griswold Controls pioneered automatic flow control with the introduction of its stainless steel flow cartridge in 1960. Over 55 years later, our innovation, quality, and reliability continue to set us apart from the competition. From the original 100% stainless steel cartridge for automatic flow controls to the Automizer the first combination actuated control ball valve with automatic flow limit controls, Griswold Controls is the leader in HVAC technology for flow control.
