Technical Information - Type 'D60' Series
The ‘ROMA’ Type ‘D60’ Float Valve is hydraulically operated, single seated, piston actuated, internal pilot and float controlled.
At full supply level, inlet pressure is retained within the piston chamber by the pilot valve, equalising pressures across the piston, and permitting inlet pressure to close the valve.
As supply level falls, the pilot valve discharges internal pressure allowing inlet pressure within the valve to act upon the larger piston area to lift the valve to a modulating opening.
The angle type Fig. No. 145A valve is ideally suitable for end of line services in make-up water and service water tanks, etc., whereas the globe type Fig. No. 145 in the larger sizes are used for surface reservoirs.
Water supply authorities and industry throughout Australia accept the robust reliable design and construction which utilises proven materials.
