8. Tips continued INSTALLATION Diaphragms leak a small amount due to migration of gas through the diaphragm material To allow escape of this gas be sure casing vents where provided remain open Use control lines of equal or greater size than the control tap on the regulator If a long control line is required make it bigger A rule of thumb is to use the next nominal pipe size for every 20 feet 6 1 meters of control line Small control lines cause a delayed response of the regulator leading to increased chance of instability 3 8 inch OD tubing is the minimum recommended control line size When using relief valves be sure to remember that the reseat point is lower than the start to bubble point To avoid seepage keep the relief valve setpoint far enough above the regulator setpoint Vents should be pointed down to help avoid the accumulation of water condensation or other materials in the spring case Make control line connections in a straight run of pipe about 10 pipe diameters downstream of any area of turbulence such as elbows pipe swages or block valves When installing a working monitor station get as much volume between the two regulators as possible This will give the upstream regulator more room to control intermediate pressure For more Regulator Tips turn to page 664 of the Industrial Application Guide Edition VI or log on to www fisherregulators com Emerson s sales service and techni

12. Do not oversize regulators Pick the smallest orifice size or regulator that will work Keep in mind when sizing a station that most restricted trims that do not reduce the main port size do not help with improved low flow control Most soft seated regulators will maintain the pressure within reasonable limits down to zero flow Therefore a regulator sized for a high flow rate will usually have a turndown ratio sufficient to handle pilot light loads during off cycles Do not undersize the monitor set It is important to realize that the monitor regulator even though it is wide open will require pressure drop for flow Using two identical regulators in a monitor set will yield approximately 70 percent of the capacity of a single regulator TEMPERATURE Most regulators shown in this handbook are generally suitable for temperatures to 180 F 82 C With high temperature Fluorocarbon FKM if available the regulators can be used for temperatures to 300 F 149 C Check the temperature capabilities to determine materials and temperature ranges available Use stainless steel diaphragms and seats for higher temperatures such as steam service For every 15 psid 1 0 bar differential pressure differential across the regulator expect approximately one degree drop in gas temperature due to the natural refrigeration effect Freezing is often a problem when the ambient temperature is between 30 F 1 C and 45 F 7 C Regulator

SPHERIC PRESSURE EE LOADING PRESSURE Figure 2 Pilot Operated Regulator Pilot Operated regulators are preferred for high flow rates or where precise pressure control is required A popular type of pilot operated system uses two path control In two path control the main valve diaphragm responds quickly to downstream pressure changes causing an immediate correction in the main valve plug position At the same time the pilot diaphragm diverts some of the reduced inlet pressure to the other side of the main valve diaphragm to control the final positioning of the main valve plug Two path control results in fast response and accurate control Pressure Reducing Regulator Selection The majority of applications require a pressure reducing regulator Assuming the application calls for a pressure reducing regulator The following parameters must be determined Outlet pressure to be controlled e Inlet pressure to the regulator Capacity required Shut off capability required Process fluid Process fluid temperature Accuracy required Pipe size required End connection style Material requirements Control line needed Overpressure protection Relief Valve Backpressure Regulator Relief Valves and Backpressure Regulators A pressure relief valve is a control device that opens to relieve fluid to atmosphere during an overpressure occurrence A backpressure regulator is a control device that maintains a c
