This Pressure Relief Valve has a hex type adjustment screw in the center of the top dial.
The top dial is in a step configuration and each step is labeled with a number from 75 PSI to 250 PSI in 25 PSI increments.

After setting your desired pressure, test your settings prior to placing the unit in service.
Make sure all personnel are clear of the appliance when testing your settings. Over pressurizing the hose lines and appliances may lead to malfunction or failure of the appliance or connections, which may lead to injury or death.
