1931 Description of two special float-controlled Larner-Johnson valves supplied by M J. Blakeborough and Sons in connection with the Sugar Loaf-Rubicon Hydroelectric scheme in Victoria. 'These valves were intended to supply balancing tanks for compensation water, and were required to operate under rather unusual conditions. It was specified that the valves should be closed with the reservoir water at the highest level, opening on a fall of level, and that they should remain open through any further fall, to a determined amount, closing again if the level fell still further, and remaining closed until the normal level was restored. Two such valves were supplied, both with an outlet diameter of 8 in., capable, under a head of 20 ft., of passing approximately 175,000 gallons per hour. One valve was installed at Beech Creek and the other at Lubra Creek, and both are adjusted to open fully on a fall of reservoir level of 1-24 ft. They are, however, arranged so that the main valve commences to open at different levels in the two cases. ......'[5]
