About Adjustable Relief Valves

Install these relief valves to protect systems, lines, and equipment from pressure extremes. They open at a preset pressure to divert a portion of fluid from the main line into a separate line to keep the system pressure from rising. You can easily adjust the pressure at which the valve opens.

Quickly adjust the pressure setting using the handwheel.
