Thermostatic type, such as bellows type or wax type, is used.

temperature change is good, condensate retention is quite small and condensate is discharged quickly.

impact pressure of water hammer, etc. What is Cold and Hot Water Valve?

3 What is Radiator Trap? It is a trap mainly installed at condensate outlet side of radiator for steam heater. Thermostatic type, such as bellows type or wax type, is used. Because heat sensitive area sensing temperature is larger than wax type, and responsiveness of temperature change is good, condensate retention is quite small and condensate is discharged quickly. Wax type Because sensor which senses temperature is capsule wax type, its structure is effective for impact pressure of water hammer, etc. What is Cold and Hot Water Valve? It is used with installed on heat release equipment using cold and hot water mainly. By regulating valve opening constant, it can be used as return valve. What is Radiator Valve? It is used with installed on heat release equipment of heater, which uses steam mainly. Flow rate can be regulated manually. -3

17 1 Series Flow Rate Chart KV value P: Pressure loss MPa Difference from set temperature Hot water flow rate is about 0 L/h, when ΔP = MPa and temperature decreased 2K (2 C) from set temperature. <Installing example> <Handling cautions> Do not install the sensor to valve during construction, since the valve and sensor are separated. Surely fix the sensor and valve after construction. Flush well the radiator and pipes in order to avoid scale problem inside the system. Please install the sensor at the place where precise temperature sensing is possible. The valve may not able to operate stably, if it is installed at the backward of curtain, furniture or radiator panel. Also when exposed to direct sunlight or draft. Install the sensor sideways. -17
