Smarter Pneumatics for Sustainable Water & Wastewater Operations

Water infrastructure demands automation that can operate reliably under challenging conditions — including corrosive environments, high flow volumes, and continuous duty cycles. At Duncan Engineering, we provide robust, corrosion-resistant pneumatic valves and actuators that deliver precision and reliability across every stage of the water cycle.

Where our solutions work

Raw Water Intake & Pumping

Process: Draws water from rivers, lakes, or reservoirs and transfers it to treatment facilities. Requires dependable valve control for pump protection and flow regulation.
