Balanced 2-way Control Valves type L1SBRGun Metal, PN 16, DN 15 – 32 mm, Reverse acting2.2.04.01-BGB-1Characteristics• Nominal pressure PN 16• Regulating capability k vsk> 25vr• Single seated, balanced• Quadratic characteristic• Pressure balanced control valveApplicationsBalanced control valves type L1SBR arede signed for regulation of cooling water,sea water and lubricating liquids.Balanced valves are used in installationswhere the system pres su re necessitatesa closing for ce greater than availablein the actuator pro gram me for a standardsing le sea ted valve, and where theleakage rate for a double-seated valveis unac cep tab le.The valves are installed combined withour self-acting thermostats, pressuredifferential regulators or electric valveactuators for regulation in central heatingplants, industrial plants, industrial processesor marine installations - especiallyin control systems for cooling.The reverse acting valves are held inclosed position by means of a built-inspring.Bar1615.5Pressure/Temperature diagramAccording to DIN 2401DesignThe valve components - spindle, seatsand cone - are made of stainless steel.The valve body is made of gun metalRG 5.The thread for the actuator connection isG1B ISO 228. The valve is single seated,balanced. The leakage rate is less than0.05% of the full flow (according to VDI/VDE 2174).Quality assuranceAll valves are manufactured under an ISO9001 certification, and are pressure andleakage tested before shipment.FunctionWithout the actuator being connected,the valve is held in closed position bymeans of a spring. With pressure on thespindle the valve opens.In connection with our thermostats thevalves will open at rising temperatures.In connection with our valve motors thevalves will either close or open dependingon the application.The quadratic characteristic will notcease, until the flow has dropped below4% of the full flow.Technical dataMaterials:- valve body Gun metal RG 5- components Stainless steelNominal pressure PN 16SeatingSingle seatedValve characteristic QuadraticLeakage≤ 0.05% of k vsTemperature range See pressure/temperaturediagramMounting See page 2Internal connectionthreads ISO 7/111SpecificationsTypeConnectionthreadsDNmmOpeningmmk vs -valuem 3 /hLifting heightmmWeightkg15 L1SBR Rp ½ 15 15 2,75 6 1.020 L1SBR Rp ¾ 20 20 5 6.5 1.325 L1SBR Rp 1 25 25 7.5 7 1.60 100 130 200oC32 L1SBR Rp 1¼ 32 32 12.5 8 2.9Subject to change without notice.Clorius Controls A/STempovej 27 · DK-2750 Ballerup · DenmarkTel.: +45 77 32 31 30 · Fax: +45 77 32 31 31E-mail: mail@cloriuscontrols.comWeb: www.cloriuscontrols.com

For valve temperaturesabove 170ºC, a cooling unitof type KS 4 has to be applied and thethermostat/actuator must be fitted belowthe valve.The device has a built-in stuffing box.For sealing and manual operation ofvalves when an actuator has not beenfitted, e.g. during periods of construction(max. 170ºC).Cooling Unit KS-4H1HG1BStrainerIt is recommended to use a strainer infront of the control valve if the liquid containssuspended particles.Cooling unit protecting the stuffing boxof the motor/thermostat.
