4. Control of Shut-off Valve
5. About the Pressure Regulating Valve
The Pressure Regulating Valve is an important device to reduce spraying pulse, maintain the constant pressure, ensure even spraying, minimize environmen-
tal pollution and enhance the pest control performance.
The Pressure Regulating Valve is normally-closed with its open pressure set at 1.4±0.2bar， and close pressure set at 1±0.15bar. When the pressure inside
the tank increases to above the set open pressure, the sprayer starts spraying by holding down its shut-off valve. When the pressure is lower than the close
pressure, the regulating valve will shut-off by itself and stop spraying. You shall inflate the tank if you desire to proceed to spray.
Note: Residual pressure will be maintained in the tank even upon the finish of spraying due to the regulating valve. Please release the pressure before
removing the pump by following the instructions (as given in the Relief Valve)
6. Relief Valve
Relief Valve is an important part of the Air-compressed Sprayer. When the pressure inside the tank exceeds the set
value, the Valve will open by itself to discharge a certain amount of air quickly to maintain the internal pressure below
the set value and ensure reliable and safe operation.
Note: You may lift the valve thimble of the relief valve to relieve the residual internal pressure before removing the
pump.
