    24. Installation Any position (horizontal is optimum) Blow out the system Introduce fluids slowly Position for easy maintenance & repair Use 2 valves when pressure reduction is greater than 4 to 1

    25. Multiple & Parallel Installation When to use parallel installation Situations of wide demand variations so reducing wear on large regulator Better assurance of continuous water supply in critical installations Less costly on original installation Easier maintenance When low flow is less than 10% of the valve capacity

    26. Multiple & Parallel Installation

    27. Multiple & Parallel Installation Selecting the regulators Determine the flow rate Select regulators totaling the flow rate required Determine the regulator pressure settings Fall off Set smaller one 10psi higher

    28. Multiple & Parallel Installation Regulator size All regulators the same size Provides most advantages Only partially more efficient Different size regulators One valve operates at low flow and both at high flow Both valves work at near capacity

    29. Troubleshooting Pressure builds downstream Thermal expansion of water during heating Foreign matter in seat/disc area Cut, worn or scored disc Damaged seat

    30. Troubleshooting Fluctuating pressure at downstream fixtures Low water pressure in street mains Heavy periodic demand

    31. Troubleshooting Inadequate flow from fixtures Pipelines to fixtures may be inadequate House main supply may be inadequate PRV may be adjusted too low PRV may be the wrong size Strainer could be fouled or clogged

    32. Troubleshooting PRV hums, whistles or chatters High velocity of flow Worn or loosely assembled seat disc Low demand verses large size PRV

    33. Troubleshooting Leakage through weep hole or adjusting screw Ruptured or cut diaphragm Diaphragm assembly loose

    34. Overview Regulators may be balanced or unbalanced They absorb energy which gives creates fall-off (droop) Flow is a function of pressure drop Always size for the worst condition (highest flow at the lowest pressure drop) Regulators usually fail in the open position

    35. Hot Water Supply Systems 1 lb. Nitroglycerine = 2,000,000 ft. lbs. Explosive energy 1 lb. Water (flashed into steam) = 750,000 ft. lbs. Explosive energy
