Adjustment of the opening pressure of the relief valve:
1. Before leaving the factory, the opening pressure of the relief valve should be adjusted one by one to the set value required by the user. If the user proposes the working pressure level of the spring, it should generally be adjusted according to the lower limit value of the pressure level before leaving the factory. 2. Before installing the relief valve on the protected equipment or before installation, the user must readjust it at the installation site to ensure that the set pressure value of the relief valve meets the requirements. 3. Within the working pressure range of the spring indicated on the nameplate, the opening pressure can be adjusted by rotating the adjusting screw to change the spring compression amount. 4. Before rotating the adjusting screw, the inlet pressure of the valve should be reduced to less than 90% of the opening pressure to prevent the valve disc from being driven to rotate and damaging the sealing surface. 5. To ensure accurate opening pressure values, the medium conditions during adjustment, such as medium type and temperature, should be as close as possible to the actual operating conditions. The type of medium changes, especially when the accumulation state of the medium is different, and the opening pressure often changes. 6. Conventional relief valves are used to fix the additional back pressure. When the opening pressure is adjusted after inspection (the back pressure is atmospheric pressure), the setting value should be the required opening pressure minus the additional back pressure.
