動態平衡電動二通閥在製冷和供熱系統中，風機盤管通常由電動二通閥控制。當一些風機盤管關閉時，其他執行的風機盤管流量進口動態平衡電動二通閥2.jpg將增加，引發室溫波動。stv系列是集動態流量平衡閥和電動二通閥於一體的產品，由電熱執行器控制。在閥門開啟時，通過動態平衡閥的恆流作用維持流經裝置的流量不變而不受系統壓力波動的影響，使控制精度更高。在製冷或供熱系統中，當室溫達到房間溫控器設定值時，房間的溫控器傳送訊號到電熱執行器，令閥門關閉。當室溫高於或低於設定溫度時，房間溫控器傳送訊號到電熱執行器，令閥門開啟。通過閥門關閉和開啟，使室溫始終保持在房間溫控器設定的溫度範圍內。內建平衡閥芯會自動保持流量恆定 retz dynamic balance electric two-way valve in refrigeration and heating systems, fan coil units are usually controlled by electric two-way valves. when some fan coils are closed, the flow of other fan coils in operation will increase, causing room temperature fluctuations. stv series is a product integrating dynamic flow balance valve and electric two-way valve, which is controlled by electric actuator. when the valve is opened, the constant flow of the dynamic balance valve keeps the flow through the equipment unchanged without being affected by the system pressure fluctuation, so that the control accuracy is higher. in the refrigeration or heating system, when the room temperature reaches the set value of the room temperature controller, the room temperature controller sends a signal to the electric actuator to close the valve. when the room temperature is higher or lower than the set temperature, the room temperature controller sends a signal to the electric actuator to open the valve. by closing and opening the valve, the room temperature is always kept within the temperature range set by the room temperature controller. the built-in balance valve core will automatically keep the flow constant.
