Thermostatic Radiator Heating System Pneumatic Temperature Control Valve, 501 Original

Features: The temperature sensing element can be very sensitive to the small change of room temperature (such as electric heating, solar radiation, etc.) and automatically adjust the flow to reach a comfortable temperature range, without wasting a minute of your heat.Specifications:Material: ABSSize: 91 * 41 * 41mm/3.58*1.61*1.61\"Purpose:for valve controlWorking principle:When the room temperature rises, the temperature sensing element expands due to heat, compressing the valve rod makes the valve close. When the room temperature drops, the temperature sensing element shrinks due to cooling, and the valve rod bounces back to make the valve open.Notes:1. Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!2. Please allow 1-3cm measuring deviation due to manual measurement.1 X Temperature Control Valve
