1. To avoid such injury and damage install the backpressure regulator in a safe location Clean out all pipelines before installation of the backpressure regulator and check to be sure the backpressure regulator has not been damaged or has collected foreign material during shipping For NPT bodies apply pipe compound to the male pipe threads For flanged bodies use suitable line gaskets and approved piping and bolting practices Install the backpressure regulator in any position desired unless otherwise specified but be sure flow through the body is in the direction indicated by the arrow on the body Note It is important that the backpressure regulator be installed so that the vent hole in the spring case is unobstructed at all times For outdoor installations the backpressure regulator should be located away from vehicular traffic and positioned so that water ice and other foreign materials cannot enter the spring case through the vent Avoid placing the backpressure regulator beneath eaves or downspouts and be sure it is above the probable snow level Overpressure Maximum inlet pressures depend upon body materials and temperatures Refer to the nameplate for the maximum inlet pressure of the valve The valve should be inspected for damage after any overpressure condition Fisher backpressure regulators are NOT ASME safety relief valves Startup The backpressure regulator is factory set at approximately the midpoint of2. the spring range or the pressure requested so an initial adjustment may be required to give the desired results With proper installation completed and relief valves properly adjusted slowly open the upstream and downstream shutoff valves if applicable Adjustment To change the outlet pressure remove closing cap or loosen the locknut and turn the adjusting screw clockwise to increase outlet pressure or counterclockwise to decrease pressure Monitor the outlet pressure with a test gauge during the adjustment Replace closing cap or tighten the locknut to maintain the desired setting S EMERSON Process Management D100405XENG Type H800 Table 1 Maximum Allowable Inlet Pressure to 67 Series Regulators with Type H800 Backpressure Regulator to prevent Instrument Supply Pressure From Exceeding 50 psig 3 4 bar MAXIMUM ALLOWABLE INLET PRESSURE TO SUPPLY PRESSURE REGULATOR TYPE H800 INSTALLATIONS A 67 67R 67F 67FR 67AF Yes or 67AFR No SUPPLY PRESSURE 1 REGULATOR TYPES REMOTE VENT PIPING Yes 67 67R 67AF or 67AFR No Yes 67FR or 67F 1 Limit vent piping to 30 equivalent feet 9 equivalent meters of 1 2 inch piping Lower vent piping may reduce the maximum allowable inlet pressure to supply pressure regulator Parts List Key Description Key Taking Out of Service Shutdown Description MN WARNING 6 Disc Restriction 1 Relief Valve Body To avoid personal injury resulting from sudden
