False How you benefit... Good economy 1. Clorius thermostatic temperature controllers are self- acting and require no external power supply. This means no running costs and minimum installation costs. 2. Clorius thermostatic temperature controllers respond accurately and quickly to load changes due to their direct acting liquid system. Flexibility 3. Clorius thermostatic controllers can be delivered with different proportional bands fitting any control requirement. 4. Clorius thermostatic valves can be supplied from 4 mm up to 150 mm. 2- way and 3- way valves are available in gun metal, cast iron, nodular cast iron or cast steel. 5. The valves can be supplied for working pres-sures up to PN 40 and maximum operating temperatures of 350° C, making them suitable for water, steam and hot oil systems. 6. The seat and cone design ensures a quad-ratic characteristic, providing excellent control at all loads. 7. Clorius thermostats can be supplied with three different closing forces: Type V2: 200 N Type V4: 400 N Type V8: 800 N 8. Clorius thermostats can be supplied with rod or spiral sensors with threaded or flanged connections. Sensors are made in copper or stainless steel. 9. Clorius thermostats are available with setting ranges between - 30° C and 280° C. 10. Clorius thermostats can be supplied with capillary tubes in lengths up to 21 m in either copper, stainless steel or PVC- covered copper. Good economy Flexibility Reliability Serviceability Reliability 11. State- of- the- art mechanical technology and sturdy design ensure optimum reliability and accuracy, and give the thermostatic tempera-ture controllers a long life. 12. Clorius direct acting thermostat systems have a very narrow neutral zone ( 1.5° C - 2.5° C) compared with bellow systems. 13. The use of a solid piston with a single “ O” ring instead of bellows secures maximum actua-tor force and allows for complete on- site maintenance, if required. 14. In case of excessive temperatures a built- in safety spring will compensate for any ad-ditional expansion in the thermostat’s liquid system thereby preventing it from failure. One look at the controller will indicate whether the thermostat is exposed to excessive tem-peratures as the cylinder protrudes from the setting element. Serviceability 15. No special tools are required for servicing Clorius thermostatic temperature controllers. 16. The stuffing box is an integral part of the thermostatic element for easy and simple maintenance of the valve. 17. Clorius thermostats can be calibrated to ensure that scale values correspond to the value at the sensor. 18. Glycerin is available at local supermarkets etc. for refilling of the Clorius thermostat. In emergencies even water may be used. 19. An optional manual adjusting device is also available for continuous operation of the valve during installation, repair and mainte-nance of the Clorius thermostat. 20. Our customers can easily adjust the tempera-ture range of the Clorius self- acting controllers. 21. Clorius thermostatic temperature controllers can generally be repaired on- site, if required.

False The thermostatic temperature controller, which consists of a thermostat and a valve, is used for controlling temperatures in central heating and district heating systems, industrial plants or ma-rine systems. It can be used for the control of cold or hot water, steam or oil, in heating or cooling systems. A thermostat consists of a sensor and a capillary tube filled with liquid, and an adjusting cylinder. The thermostat is self- acting and based on the principle of liquid expansion; it has a sturdy design and operates with a large closing force. The adjusting cylinder of the thermostat is set at the How does it work? Valve Temperature Scale Temperature Sensor Spindle Packing Protection Bellow O- Ring Piston Temperature Override Spring Cylinder Adjusting Handle Liquid Filling Capillary 3- 21 m required temperature for the heated medium in ° C. The temperature control is carried out by the ther-mostatically controlled valve reducing or increasing the flow of the heating ( or cooling) medium. If the temperature of the medium to be heated is above the required level, the sensor liquid expands, causing the piston of the thermostat to act upon the valve, reduc-ing the flow of the heating medium. If the temperature of the medium to be heated is be-low the required level, the temperature of the sensor liquid falls, reducing the volume of the liquid, so that the piston allows the valve to open under its internal spring, thus increasing the flow of the heating medium.
