Civil Engineering June 2022 19 Figure 12 Top-hung diaphragm locally made inlet control valve (small reservoirs) flow limiting valves. The latter comprise purpose-made multiple flexible orifice grommets embedded in a PVC or stainless steel flange (installed between flanges anywhere on the inlet pipework) which deflect to become exponentially more restrictive beyond the design rate of flow. The stainless steel control valves are either top-hung (small reservoirs) or through-the-floor mounted; both with a robust float controller mounted next to a roof access manhole.  Exceptional service timeous unmatched experience delivery Telephone: +27 31 705 7935 Fax: +27 86 513 2352 Email Address 1 : amathongace@hotmail.com Website: www.amathonga.co.za Physical Address : 71 Qashana Khuzwayo Road, Suite 10 Maxbridge Centre, New Germany, 3620 Postal Address: P.
