Features and BenefitsFor system applications that require largedischarge release capacities, the Consolidated13900 Series Safety Relief Valve provides extremelyreliable working economy and a simple efficientvalve design. It also features a valve configurationthat simplifies installation and in-line valvemaintenance.Greater Total System EfficiencyThe main valve can handle extremely large relievingcapacities, in excess of 3 million pounds of steam perhour (1,360,777 kg/hr). It has a seven-to-one dischargecapacity over a “T” type orifice, and a two-to-onedischarge capacity over a “W” type orifice.Improved DesignThe total valve external configuration is considerablysmaller in size, and the valve is lighter in weight thana comparable spring-loaded valve. Because of thesefeatures, less space is required for valve installation.A simple, efficient and reliable direct acting valvedesign with few components eliminates the needfor excessive spare parts inventory and reducesmaintenance time.Easy Installation and MaintenanceValve configuration is considerably smaller in size andlighter in weight than a comparable spring-loadedvalve. This makes installation, field handling, testing,and valve maintenance easy.Valve maintenance is relatively simple andstraightforward. The simple valve design meansfewer parts. Fewer valve parts mean that less can gowrong, malfunctions can be readily diagnosed, andmaintenance costs and process downtime can bekept to a minimum.To simplify valve maintenance, all main valvecomponents can be removed through the top bonnetof the valve. The pilot valve can be field tested andrepaired without breaking inlet and outlet pipingconnections on the main valve. The pilot valveopening and closing is easily adjusted on a small testfacility.DescriptionThe 13900 Series Pilot-Operated Safety Valve is anASME Section VIII-approved valve intended for useon compressible fluids. The valve design is simple. Itconsists of a small conventional, fail-safe pilot safetyvalve and main valve.Overcompression of the main valve seat O-ring,located between the disc and bushing, is eliminatedby the metal- to-metal contact bearing surfacesbetween the disc and bushing. Removing the pressurefrom behind the O-ring via two small slots when thevalve is open and flowing eliminates O-ring sealblowout. A condensate drain hole in the disc easilydrains any accumulated moisture in the upper disccavity.The spring-loaded U-shaped PTFE guide sealprovides increased seat tightness as system pressureincreases. The PTFE material greatly reduces friction onthe main disc and allows for reliable, dependable andrepeatable disc action. The seal spring load ensuressealing at all times.PTFE guide rings eliminate friction along with metalto-metal contact between the disc and guide. Mainvalve disc action is repeatable and reliable.The pilot valve action directly controls the pressureforces on the main valve disc and eliminates the needfor a transfer valve. System pressure that actuatesthe pilot valve is transmitted through a simple, fullflow design sensing tube. The sensing tube eliminatessmall orifice control parts and their possible cloggingcharacteristics and is enclosed within the valve body,which protects it from damage and freezing.Pilot valve blowdown can be adjusted independentlyof the main valve and before the pilot valve is installedon the main valve.The pilot valve disc is a metal-seated design that iseasily serviced and provides a seat tightness to 95percent of set pressure.The main unloading valve has a large orifice of upto 200 in2 (1290 cm2), which reduces the numberof valves required for overpressure protection. Thiseliminates installation costs for additional headernozzles and exhaust lines.The O-ring seat seal design and the spring-loadedPTFE rings assure tightness, valve integrity, and easyvalve maintenance.4 Baker Hughes 2020 Baker Hughes Company.

Applications The 13900 Series Pilot-Operated Safety Relief Valveis designed for steam applications where pressuresrange from 50 psig (3.45 barg) to 300 psig (20.68barg) and temperatures range from 250 F (121 C)to 550 F (288 C). The temperature limit is appliedto the valve to ensure that the PTFE seal rings willmaintain sealing integrity. The 13900 Series Pilot-Operated Safety Relief Valvecan be used on any compressible fluid withinthe pressure and temperature limits of the valve,provided the fluid media exhibits characteristicssimilar to saturated steam. For applications otherthan steam, the open lift lever cap should bereviewed for adequacy. If another cap design isrequired, it should be so stated. For all sizes except the 200 in2 (1290 cm2), thelargest possible relieving capacity is supplied forthe valve inlet size specified. For those applications where discharge pressuresat the valve outlet exceed 10 percent of the pilotvalve set pressure, or where economics dictatethat higher discharge pressures be required, thepilot valve can be exhausted separately and thedischarge pressure of the main valve can beallowed to increase above the limit of 10 percent ofthe pilot valve set pressure. Typical valve applications include boiler feed pumpturbines, flash tanks, steam lines and deaerator.CAUTION The 13900 Series Pilot-Operated Safety Relief Valveis available in four sizes, 114, 143, 176 and 200 in2 (735,923, 1135 and 1290 cm2).These valves are not to be used onpower boilers.Scope of Design13900 Flanged Series Pilot-Operated Safety Relief ValveStandard Valve ConnectionsValveType1.InletOrifice s16.00406.4300# R.
