Thermostats of stainless steeltypes V4.03 and V4.053.4.05-EGB-1Characteristics• Self-acting• P-controller• Completely sealed• Excess temperature protection• All parts made of stainless steel• Non-magneticApplicationThe thermostat is particularly suitable forinstallation in demanding environmentssuch as tank installations, outdoor plantsand where it must be non-magnetic, e.g.in submarines.FunctionThe adjusting cylinder of the thermostatis set at the temperature in ºC for therequired heated medium. The temperatureis regulated by the thermostaticallycontrolled valve reducing or increasingthe flow of the heating medium. Togetherwith the adjusting cylinder, the liquid-filledsensor and capillary tube constitute aclosed system.If the temperature of the medium to beheated is above the required level, thesensor liquid expands, causing the spindleof the thermostat to act upon the valve,thereby reducing the flow of the heatingmedium.If the temperature is below the requiredlevel, the temperature of the liquidin the sensor decreases and thevolume is reduced, thereby the valvespring opens the valve causing anincreasing flow of the heating medium.ConstructionThe parts of the thermostat are made ofstainless steel. The thermostat consistsof a liquid-filled sensor, a capillary tube,and an adjusting cylinder.The adjusting cylinder has O‐ring sealingsand is sealed with silicone glue at the topfor hermetical closure. The thermostat isavailable with settings between -30ºCand +280ºC.At flow temperatures above 170ºC, acooling unit must be installed betweenthe valve and the thermostat. Pleasesee datasheet no. 8.5.00.Neutral ZoneThe neutral zone of the thermostat,which is less than 2ºC, is the temperaturedifference which can accur at the sensorwithout the thermostat spindle beingactuated.Sensor typesRod or spiral sensors of stainless steelwith pipe thread.Sensors are also available with a packboxon the capillary tube for applicationswhere the sensor is to be lowered into atank etc.Sensor liquidGlycerine at a scale range between - 30ºCand 160ºC.Paraffin at a scale range between 140ºCand 280ºC.Capillary tubeThe capillary tube is made of stainlesssteel and is available in lengths from 3 mup to 21 m.ValvesThe thermostat may be used for valvesup to DN 150 mm for heating and coolingplants.See data sheet "Quick choice of temperaturecontroller" no. 9.0.00 and datasheet for the particular valve.Technical dataMax. closing force 500 NStandard settings:-Type V4.03 0-160 ºC-Type V4.05 0-120, 40-160 ºCReinforcement (mm/ºC):(Glycerine) Type V4.03: 0.3Type V4.05: 0.5(Paraffin) Type V4.03: 0.33Type V4.05: 0.7For valves withlifting height up to 21 mmSensor material W.
