Corrugated pipe safety valve adjustment safety technology operation flow

① safety valve factory, should be adjusted one by one the opening pressure to the user requirements of the setting value. If the user to spring working pressure level, the pressure level should generally be adjusted to the lower limit of the factory.

② Before installing the safety valve on the equipment to be protected or before installation, the user must re-adjust at the installation site to ensure that the set pressure value of the safety valve to meet the requirements.

③ in the nameplate indicated by the spring working pressure level range, by rotating the adjustment screw to change the amount of spring compression, you can adjust the opening pressure.

(4) Before adjusting the screw, reduce the valve inlet pressure to less than 90% of the opening pressure to prevent the disc from being rotated when the adjustment screw is rotated, thus damaging the sealing surface.
