Pressure relief valves are used to control and limit the pressure build-up in a system. To do this properly, you’ll need an air pressure gauge to test the existing pressure of your expansion tank. Adjust the set pressure or vacuum level within the range. As stated above this valve gets into action when the air pressure reaches a dangerous level. This is because it is a control valve that will be able to reduce and increase the airflow that is coming out of the air compressors tank. They begin closing as pressure or vacuum level drops and fully close when the system is restored below the set point. The air conditioning system is protected by a pressure relief valve, located on the end of the high side hose near the compressor. This video will tell you how to adjust a Pilot/Unloader Valve for your constant-run air compressor. The unloading pressure for the typical air brake system is 120 psi but it can be higher up to 130 psi without a problem. When you feel the air coming out the top of the valve that means you have set your bottom pressure setting. When the refrigerant pressure reaches an abnormal level of 540 psi (3727 kPa), the release port automatically opens and releases refrigerant to the atmosphere. Anywhere in the middle is good in my book. Adjusting the Bendix D2 governor just takes a 7/16 wrench and a screwdriver. Relief and Sequence Valves Pressure relief valves mount between the pump and valve system to protect against overloads. This is an easy adjustment … Attach the valve directly to the air inlet valve on the tank. cut-in pressure, the pilot valve closes allowing the unloading device to close and the compressor once again pumps into the receiver. A pressure regulator is a very important factor of an air compressor. Pressure relief valves, or safety valves, are a simple but critical part in any air compressor system. If you are adjusting the cut in pressure and also changing the cut out pressure, it is not a … Evidently you can fix a pressure relief valve. Jim wrote… “My harbor freight compressor high pressure release valve was opening-releasing pressure at about 110 psi even though the compressor is rated to 125 psi. These valves begin opening at the set pressure or vacuum level and fully open at about 10% over the set point. Increasing the pressure setting above the factory settings on an air compressor will lead to an early failure of the compressor, and may lead to a catastrophic compressor failure. Screw the pressure screw back into its place slowly. A suitable pilot valve may be used to “vent” the balanced piston relief valve when the system does not require power. Relieve excess pressure or vacuum with one valve that can be configured for either application. Once you’ve determined the pressure, use a hand pump to raise it to a pressure equal that of your home’s water pressure. This venting unloads the pump through the relief valve at low pressure, avoiding energy waste and Pressure Adjustment: Loosen pressure lock nut “B” and adjust pressure adjusting nut “A” to desired cut out pressure. Adjust the compressor to the minimum load pressure setting and turn the compressor off. Turn pressure adjusting nut pressure. I am appreciative of Jim who posted the following information on this site in January. Sometimes the pressure buildup in the compressor tank far exceeds the maximum level, to avoid such undesirable and potentially dangerous situations a safety relief valve is placed in the unit.
