Pressure reducing valve installation guide

INSTALLATION INSTRUCTIONS for PRESSURE REDUCING REGULATOR VALVES SERIES E3, E41, and E56 PURPOSE To reduce a higher inlet pressure to a lower outlet pressure, and automatically control the lower (or set/controlled) pressure. INSTALLATION If possible, install the valve in the upright position (see Installation Diagrams). 1. Low or Fluctuating Water Pressure. If your water pressure doesn't seem to be as strong as it once was or you notice a significant loss of pressure when you use more than one fixture at the same time, your pressure reducing valve may be bad. If you don't usually use different tubs and showers at the same time, you may first notice this - Install the Pressure Reducing Valves (PRV) vertically or horizontally (upright or inverted), but the PRV must be installed with the arrow in the direction of flow. - The valve is preset at 50 PSI. To adjust, loosen Lock Nut (2) and turn Adjustment Bolt (1) clockwise to increase, and counterclockwise to decrease. Commonly referred to as the PRV (pressure-reducing valve), the device determines the pressure at which water reaches your pipes, allowing safe flows. The good thing is that the device comes with all the necessary instructions for an easy installation. First, cut some 6 inches off your pipe after the shut-off valve. Connect the fittings on NOTE: When reducing pressure, open a down stream faucet to relieve pressure. 9. Tighten locknut when desired pressure is achieved. INSTALLATION INSTRUCTIONS Install valve in line with arrow on valve body pointing in direction of flow. Before installing reducing valve, flush out line to remove loose dirt and scale which might damage seal ring Install a steam trap at the reducing valve inlet. There is a fast closing valve near the PRV. Provide as long a distance as possible between the two valves. 3 GD-30 1/2" - 1" Disassembly 1. Eliminate pressure from inside the valve. Make sure the valve is completely free from pressure. 2.

All valves will be furnished with stock settings to reduce to 50 psi. To readjust reduced EXAMPLE BASED ON THE CALEFFI 535 SERIES PRESSURE REDUCING VALVE. The size of the pressure reducing valve is determined by means of Graph 1, starting with the design flow figure and bearing in mind that the ideal velocity is between 1 and 2 m/s (blue band). The 32mm pressure reducing valve is selected for a nominal flow rate of 98.4 l/m, which 2.Install the pressure reducing valve in any position either vertically or horizontally, not upside down, paying attention to the "direction of flow" indicator on the body of the valve. 3.Caleffi 5335 series pressure reducing valves are factory set at 500 kPa.
