This 36-inch valve with anti-cavitation trim and dual solenoids is working in tandem with a 24-inch valve to ensure the Sandy River in Oregon is cool enough for threatened salmon species to spawn.

The Bull Run Dam is one of two Portland Water Bureau dams that, combined, hold 17 billion gallons. A member of the Water Utility Climate Alliance, the bureau is one of the nation’s largest public water utilities.
