Product Information：
This Heating Temperature Valve is also a temperature control angle valve, which can control the size of the valve and automatically adjust the flow rate to achieve a comfortable temperature range.
The heating system is designed and calculated based on the maximum heat load required under the lowest outdoor temperature. However, this design temperature of the temperature control valve only occurs for a few days in the severe cold season, which means that the heating system is operating at full load only for these few days in the entire heating season. Generally speaking, the heat load required to ensure room temperature is much smaller than the design value, and the heat load is constantly changing. The daily heat load varies throughout the heating season. The Heating Temperature Valve can automatically maintain an accurate room temperature according to the predetermined requirements, without being affected by climatic conditions. Install a Heating Temperature Valve in each room to ensure that the "free" heat emitted by sunlight, lighting facilities, machinery and the human body can be fully utilized to achieve the effect of saving energy.

How to choose other valves in the heating system?
The first type of valve is a valve for closing purpose. For example, gate valves for hot water and condensate systems, shut-off valves for high and low pressure steam systems, ball valves can also be used.
The second type is the valve that regulates the system. It is recommended that you choose a globe valve, a manual control valve or a butterfly valve.
The third type is a valve used for water discharge and exhaust in the system. Personally, I suggest that you refer to the plug valve when the hot water temperature is less than 100°C; when the hot water temperature is greater than or equal to 100°C, use the gate valve.
The fourth point is for various valve connection methods. Personally, I suggest that you can use flange connection threaded connection or welding for the connection method of globe valve, gate valve or butterfly valve.
How to test the valves in the heating system
The first point is that valves used in heating systems must be tested as required before installation. The strength and tightness test should be done before the valve is installed. The test should randomly check 10% of each batch, that is, the quantity of the same brand, the same specification, and the same model, and it is not allowed to be less than one. For closed-circuit valves installed on the main pipe to cut off, the strength and tightness tests should be done one by one.
The second point is the test for situations where the design is not required. When the design requires the strength and tightness test of the valve, it should be carried out according to the following regulations. In the strength test of the valve, the pressure is 1.5 times the nominal pressure, and the tightness test pressure is 1.15 times the nominal pressure. The test pressure remains unchanged during the test duration, and there is no leakage of the shell packing and valve flap sealing surface.
The third point is that we look at the specific requirements for the shortest test duration of various valves. The first case is a metal-sealed valve. The specific requirements of the tightness test are that when the diameter is less than or equal to 50mm, the time shall not be less than 15 seconds; when the diameter is 60mm to 200mm, the time shall not be less than 30 seconds; when the diameter is 250mm to 450mm, the time shall not be less than Less than 60 seconds. In addition, for valves with non-metallic materials, the corresponding specifications above are 15 seconds, 15 seconds and 30 seconds. In addition, in terms of strength test requirements, when the diameter is less than or equal to 50mm, it shall not be less than 15 seconds; when their diameter is 60 to 200mm, it shall not be less than 60 seconds; when the valve diameter is 250mm to 450mm, it shall not be less than 180 seconds.
