  • Checking rotary valve clearances

    Rotary valves are precisely machined to accommodate very tight internal clearances. In a smaller standard valve there should be a .003” – .005” gap between the tips and ends of the rotor and the housing / headplate. However, the clearances on many valves are customized to meet the needs of a specific application. For example, in applications with temperature greater than ...

  • Reduction in water losses in water distribution systems using pressure reduction valves

    Water loss is a phenomenon frequently observed within water distribution systems (WDSs), that is considerably worsened by an excessive pressure throughout the network. As an alternative option to pipe replacement, the use of pumps working as turbines, throttle control valves (TCVs), or pressure reduction valves (PRVs) can be used to reduce leakage. For a preassigned number of these devices, ...
