Multistab Regulation Valves - Fluid Level Valve

MULTISTAB REGULATION VALVES FLUID LEVEL VALVEFUNCTION :To maintain a constant and adjustable water level in a reservoir.100 % hydraulic, proportional opening and closure.OPERATION :1 - The water level in the reservoir reaches the assigned value.2 - The drive closes.3 - Chamber C is supplied with water. The valve closes.4 - The water level in the reservoir drops between 10 and 15 cm below theassigned value.5 - The drive opens.6 - Chamber C is not supplied with water. The device opens.CONNECTION :Flanges NP 10 - 16 - 25LIMITS OF USE :Maximum upstream pressure : 10 bars. Beyond 10 bars provide a pressurereducer upstream of the device.Minimum upstream pressure : 0.3 to 0.8 barTemperature of the conveyed fluid : 0 to 90°cFLOW in l/sec :SETTING :Connect the device according to the directionof flow as indicated on the casing by an arrow.Connect the drive to the reservoir via a ductwhich must as far as possible have its sourceat one point of the static regime in normaltime.Increase or reduce the water level in thereservoir to the required value by turning thescrew on top of the drive. To increase thelevel, turn the screw clockwise. To reduce thelevel, turn anti-clockwise.PROTECTION :To ensure a perfect and lasting performanceof the device in operation, it is essential to ins-tall upstream a CM series FILTRAM type filter.LIST OF PARTSDIMENSIONS measures in mm - Weight in kgND 40 65 80 100 125 150 200 250 300 400L 280 280 300 320 350 380 450 520 590 730A 105 105 115 130 150 170 195 230 260 330H 550 550 575 630 650 680 785 810 850 890B 250 250 250 250 250 250 250 250 250 250C 200 200 210 220 230 250 280 300 330 380D 195 195 230 270 310 350 440 510 610 810Weight 45 50 55 65 85 125 150 220 290 36001 Basic sub-systemNOTICE 9602502 Stop valve R203 Fluid level driveNOTICE 9607004 Stop valve R305 Filter06 Needle valve tap07 Stop valve R108 Suction valve09 Pressure gauge connection teeND 40 65 80 100 125 150 200 250 300 400V = 1,5 m/s 02 05 08 12 18 27 047 075 105 190V = 1,3 m/s 04 10 15 24 37 53 094 150 210 380V = 1,4 m/s 05 13 20 32 49 71 126 200 280 500DRIVEDIRECTION OF FLOWRÉSERVOIR CONNECTIONL CØ 260Ø DBHA83291ND7654NOTICE96031 1/2constructeurrobinetterie industrielle250, RUE DE LA CURIAZ73290 LA MOTTE-SERVOLEXTÉL. 33 4 79 25 17 14FAX. 33 4 79 25 16 95URL : http://www.ramus-industrie.comSubject to alteration without noticeMULTISTAB REGULATION VALVES FLUID LEVEL VALVEThe water level should not fall below 1 meter.Minimum level difference between the device installation level (supply ductaxis) and the filling level (in meters).If the water supply duct reaches the reservoir at an elevated angle, the drivecan be separated from the device.OPERATION :The device closes when the water in the reservoir reaches the required fillinglevel.It opens again once the water level has gone down approximately 15 centi-meters. The difference of level between the closing and opening sequenceavoids constant operation of the device when the flow distribution demand islittle.SETTING :It is easier to adjust the filling level by simulating the water level in the reser-voir rather than by working on the reservoir itself. To do so, disconnect theRilsan drive/reservoir connection pipe at the reservoir level or replace it with alonger pipe if necessary and partly fill with water. Remove the extremity of thepipe so that the water level may correspond to the level required in the reser-voir. Induce the closure of the device by turning the adjusting screw or indu-ce the opening by turning the screw after having lowered the level by approxi-mately 15 centimeters.INSTALLATION CONDITIONS :Definition of the spring according to the water level measured between the diaphragm level and the filling level required.* The variation is proportional to the number of rotations. To increase the filling level, turn the screw clockwise. To reducethe level, turn the screw anti-clockwise.ND 40 65 80 100 125 150 200 250 300 400A 1,3 1,3 1,3 1,3 1,4 1,4 1,4 1,4 1,5 1,6SPRING FREE LENGTH 80 INTERNAL DIAMETER 31 - 5,5 6,5 7,5 8,5 9,5 10 11 12THREAD DIAMETERMAXIMUM WATER LEVEL IN METERS 2,5 3,5 5,5 8,5 12,5 16 22 26NUMBER OF SCREW ROTATIONS REQUIRED TO INCREASE 6,5 3,5 2 1,3 0,8OR REDUCE THE FILLING LEVEL BY 1 METER *APPROXIMATELY 15 CENTIMETERSWATER LEVELCLOSING LEVELFILLING LEVELOPENING LEVELDIAPHRAGM LEVELDRIVE/RESERVOIR CONNECTIONRILSAN PIPE 8/10 -(not supplied)DRAINDISTRIBUTIONSUPPLYINSTALLATION LEVELANOTICE96031 2/2constructeurrobinetterie industrielle250, RUE DE LA CURIAZ73290 LA MOTTE-SERVOLEXTÉL. 33 4 79 25 17 14FAX. 33 4 79 25 16 95URL : http://www.ramus-industrie.comSubject to alteration without notice
