Thermostatic elements of the RA 2000 series
Thermostatic elements RA 2000 series - automatic temperature control devices designed to complete the RA radiator thermostators. Radiator thermostat is a proportional direct-acting air temperature controller with a small proportionality zone, which are currently equipped with building heating systems various destination. The thermostat Ra consists of two parts:
All thermostatic elements can be combined with any regulating valves of type RA. Clip connection provides simple and accurate mounting of the thermoelement on the valve. The protective cover of thermoelements RA 2920 and RA 2922 prevents their unauthorized dismantling and reconfiguration to unauthorized persons. Specifications Radiator thermostators type RA correspond to European standards EN 215-1 and Russian GOST 30815-2002.
Specifications of thermostatic elements of the RA 2000 series
The main device of the thermostatic element is a bellows that provides proportional regulation. The thermoelement sensor perceives the change in the ambient temperature. The bellows and the sensor are filled with an easy-to-sleep liquidity and its pairs. The adjusted pressure in the bellows corresponds to the temperature of its charging. This pressure is balanced by the power of the tuning springs. With increasing air temperature around the sensor, part of the fluid evaporates, and the pressure of vapors in the bellows grows. In this case, the bellows increase in the volume by moving the valve spool towards the closing of the hole for the coolant duct into the heater until the balance between the spring force and the vapor pressure is reached. When the air temperature decreases, the pairs are condensed, and the pressure in the bellows decreases, which leads to a decrease in its volume and the movement of the valve spool towards the opening to the position in which the equilibrium of the system will again be established. Steam filling will always be condensed in the coldest part of the sensor, usually most remote from the valve body. Therefore, the radiator thermostat will always respond to changes. room temperature, not feeling the temperature of the coolant in the underwear pipeline. However, when the air around the valve is still heated by heat, given by the pipeline, the sensor can register a higher temperature than indoors. Therefore, it is recommended to establish thermostatic elements to eliminate this influence, as a rule, in a horizontal position. Otherwise, it is necessary to apply thermoelements with a remote sensor.
Select the type of thermostatic element
Thermostatic elements with built-in sensor
When choosing a thermostatic element, it should be guided by the rule: the sensor should always react to the air temperature in the room.
Thermostatic elements with a built-in sensor should always be arranged horizontally so that the ambient air can freely circulate around the sensor. Do not install them in a vertical position, since the thermal effect on the sensor from the valve body and the heating system pipe will lead to the incorrect functioning of the thermostat.
Thermostatic elements with a remote sensor
Thermostatic elements with a remote sensor should be applied if: o Thermal elements are closed with a deaf curtain; o The heat flux from the heating system pipelines affects the built-in temperature sensor; o The thermoelement is located in the draft area; o required vertical installation of thermoelement. The remote sensor of the thermostatic element must be installed on the furniture-free and curtains or on a plinth under the heating device if there are no pipelines of the heating system. When installing the sensor, the capillary tube should be pulled out to the required length (maximum of 2 m) and fasten it on the wall using the accompanying brackets or a special pistol.
Thermostatic elements of the RAW series
Thermostatic elements raw Series - automatic temperature control devices designed to complete the RA radiator thermostators. Radiator thermostat is a proportional direct-acting air temperature regulator with a small proportionality zone, which is currently equipped with systems for the heating of buildings of various purposes. The RA type thermostat consists of two parts: a universal thermostatic element of the RAW series and an adjusting valve with a pre-adjustment of the RA-N bandwidth (for two-pipe heating systems) or Ra-G (for a single-tube system).
The program of the production of thermostatic elements of the RAW series includes:
The thermostatic elements of the RAW series are equipped with system protection devices from freezing, fixing and restricting the temperature setting. RAW 5012 is equipped with an ultra-thin capillary tube with a length of 2 m, which is swept inside the sensor housing and connects a remote sensor with a thermostatic element. In the process of installation, the pipe is pulled into the required length. Clip connection provides simple and accurate mounting of the thermoelement on the valve.
The technical characteristics of radiator thermostators with thermoelements of the RAW series correspond to European standards EN 215-1 and Russian GOST 30815-2002.
In order to prevent unauthorized dismantling, the thermoelement can be fixed on the valve using a special retainer (see additional accessories).
Specifications of thermostatic elements of the RAW series
The main device of the thermostatic element is a bellows that provides proportional regulation. The thermoelement sensor perceives the change in the ambient temperature. The bellows and the sensor are filled with a special heat sensitive liquid. The adjusted pressure in the bellows corresponds to the temperature of its charging. This pressure is balanced by the power of the tuning springs. When the air temperature is raised around the sensor, the liquid is expanding, and the pressure in the bellows grows. In this case, the bellows increase in the volume by moving the valve spool towards the closure of the heat carrier duct into the heating device until the equilibrium between the spring and the fluid pressure is reached. When the air temperature decreases, the liquid begins to shrink, and the pressure in the bellows decreases, which leads to a decrease in its volume and the movement of the valve spool towards the opening to the position in which the equilibrium of the system will again be established. To eliminate the effect of warm air from heating nozzle of the heating device, it is recommended to set thermostatic elements, as a rule, in a horizontal position. Otherwise, it is necessary to apply thermoelements with a remote sensor.
Thermostatically elements of the RAW-K series
Thermostatic elements of the RAW-K series are automatic temperature controllers with a small proportionality zone. RAW-K are designed to install on the thermostators of the thermostators of HEIMEIER, OVENTROP or MNG, built into the design of steel panel radiators type Biasi, Delta, Dianorm, Diatherm, Ferroli, Henerad, Kaimann, Kermi, Korado, Purmo, Radson, Superia, Stelrad, Veha, Zehnder-Completto Fix.

dimensions
The main task of any heating system is to provide a comfortable air temperature in the room. This temperature can be different depending on the purpose of the room, but if it is a prerequisite for its immutability during the day, the thermostat becomes an indispensable structural element of the heating device.
Radiator thermostat Danfoss. Consists of two parts: valve and thermostatic element (thermal heads). Inside the thermostatic element is a thin hermetic cylinder - a belliff filled with liquid or gaseous heat-sensitive working substance. When the temperature is raised, the bellows stretch and moves the rod associated with it, which presses on the rod in the valve, and the valve reduces the coolant flow into the radiator. When the temperature decreases, the process goes in reverse order. Thus, the thermal head is the control mechanism, and the valve is executive.
Manufacturer: Danfoss (Denmark).

Thermostatic elements of Danfoss.
Thermostatic elements (thermal heads) Danfoss are automatic temperature control devices intended for a complete set of radiator thermostators.
The thermostat equipped with a thermostatic element maintains a constant temperature in the room at the desired level in the range from + 5 ° C to + 26 ° C with an accuracy of ± 1 ° C.
It should be remembered that thermostators are mostly regulatory reinforcement but not shut-off (With the exception of the thermostats RA2940 and RAW 5110), so if you need to disassemble the radiator, the thermal head should be replaced with a bronze shut-off handle, which will ensure the complete overlap of the coolant flow.

By installing thermostat, it should be remembered that the effect of their use will be tangible if they control radiators with low thermal inertia. Practically, these are all the well-known types of modern radiators besides cast iron. The latter, due to the large mass of the cast iron and the water will be heated and cool very slowly, reducing the control effect.
RLV shut-off and connecting valves are designed for lateral connection to the radiator of pipelines of a two-pipe heating system. We are produced in direct and corner execution.

Firm Danfoss. Developed thermostatic elements of the RTR 7000 series - automatic temperature control devices designed to complete the RTR radiator thermostators. The radiator thermostat is a proportional direct-action air temperature regulator with a small proportion zone, which is currently equipped with systems for the heating of buildings of various purposes.
On the radiators of your apartment, two types of control valves, RTR-G or RTR-N can be installed, depending on the specific conditions: a two-pipe or single-tube heating system (help in choosing and installing RA thermostators on radiators in your home \u003e\u003e\u003e).
After installing radiator thermostators, there is no need to open windows to regulate the temperature in the rooms. Thermostators will maintain a constant temperature in the range from 5-26 ° C, at the desired level, with an accuracy of ± 1 ° C.
Radiator thermostators guarantee the necessary water distribution over the entire heating system. At the same time, even the most remote radiators will ensure the required heat supply in the room.
