PRESSURETYPE98HMCce,at onai SchemattcPrinciple of OperationRelief or backpressure valves respond to changes inupstream pressure.Pressure changes register underthe diaphragm(see Figure 2)through a registrationhole in the valve body(through upstream sensingline connection for Type 98HM).When the pressureincreases beyond the spring setting,the diaphragmpressure overcomes the spring compression.Thiscauses the valve plug to move away from the orifice.The flow line through the valve is open and excesspressure is vented.When upstream pressure dropsback to normal,the valve resumes its closed position.InstallationPersonal injury or system damage mayresult if this relief valve/backpressureregulator is installed where serviceconditions could exceed the limitsgiven on the Specifications sectionor regulator nameplate.Installationsshould be adequately protected fromphysical damage.Ty p e s 98L a n d 98H Re l e f Se f Pr e s s u r e Ra 刀 g e sTYPE98H RELl EF s ETPREs s

injury and property damagecould occur due to fi re or exolosion ofvented gas that may have accumulated,To prevent such injury or damage.provide piping or tubing to vent the gasto a safe,well-ventilated area.Also,whenventing a hazardous gas,the piping ortubing should be located far enoughaway from any buildings or windows soto not create a further hazard,and thevent opening should be protected againstanything that could clog it.lf remote venting is necessary,an opt onal tapped ventin the spring case is available.Install remote vent linesin the spring case and outlet openings The vent linesmust have the largest practical diameter and be as shortas possible with a minimum number of bends or elbows.StartupKey numbers are shown in Figures 3 through 5.Withproper installation completed and system equipmentproperly adjusted,close any vent valves,and slowlyopen the upstream shutoff valve while using pressuregauges to monitor pressure.lf set pressure adjustment is necessary,monitor theinlet pressure with a gauge during the adjustmentprocedure.Loosen the locknut(key 17),and turnthe adjusting screw(key 6)clockwise to increase orcounterclockwise to decrease the

theindicated range is required,substitute the appropriatespring.Be sure to label the valve to indicate the newpressure range.Always use a pressure gauge to monitor pressurewhen making adjustments.All regulator springs can be backed off to 0 psig(0 bar).Recommended set pressure ranges available,maximum inlet pressures and temperatures,andcolor codes of the respective springs are shown in theSoecifications section and Tables I and 2.Loosen the locknut(key 17).To increase the setting,turn the adjusting screw(key 15)clockwise.Turn theadjusting screw counterclockwise to decrease

such as the O-rings,gaskets,diaphragm,orifice,and valve plug should beinspected periodically and replaced as necessary.Thefrequency of inspection and replacement depends uponthe severity of service conditions or the requirements ofstate and federal lawslnstructions are given below for disassembly of theTypes 98L and 98H backpressure regulators/reliefvalves.These valves do not have to be removedfrom the pipeline to inspect internal parts.Suitablelubricants are indicated on the assembly drawings.Apply the lubricants as the relief valve is beingreassembled.Refer to Figures 3,4,and 5
