Regulation 58. Pressure reducing valve.

(1) Where an unfired pressure vessel is supplied at a pressure greater than its authorised safe

working pressure, a pressure reducing valve shall be fitted between the source of pressure and

the unfired pressure vessel, so adjusted as to prevent the authorised safe working pressure of the

vessel being exceeded.

(2) For the purpose of paragraph (1) of this regulation any set of unfired pressure vessels

supplied through a single pipe may be treated as one unfired pressure vessel if the reducing

valve is fitted on such single pipe.

(3) Every reducing valve shall be fitted with a suitable safety valve and a suitable pressure gauge

adjacent thereto on the low pressure side.
