How Do I Change the Relief or Bypass Setting on a Valve?
Always use a pressure gauge in the inlet to assure precise results. An SBA valve may be adjusted by turning the adjustment screw under the acorn nut on the handle end of the valve. Clockwise will increase pressure.
The Converta or CA relief is a ball and spring type and is shim adjustable. Shims in the relief cap may be added or removed to increase or decrease pressure. The spring in the Converta is rated to 2250.
Do not exceed the recommended psi for the valve!
