          螺紋電動動態平衡兩通閥

          KV210系列螺紋電動動態平衡兩通閥
          Series Dynamic Balancing Electric Two-way Valves

          電動動態平衡調節閥 Dynamic Balancing Electric Valves

          概述 Description

          保證系統壓力變化過程中二通閥流量確定不變,使二通閥和末端盤管曲線形成良好的線性,使閥的開度與能量的調節形成很好的對應關系得到快速準確的控制,使系統的供熱或制冷達到最良好的運行效果。

          Ensure the pressure of the two sides of the adjusting valves invarable. Make adjusting valves and terminal coil unit curves form good linearity. Make the openimg of valves and adjustment of energy corresponds well to gain fast control. Make the heating and cooling system achieve the best operation results.

          l特點 Features

          集動態流量平衡閥及電動二通閥的功能為一體,在變流量系統中,調節快速準確,結構緊湊,使用壽命長,安裝簡便,減少能源消耗。

          動能平衡電動二通閥與室內溫控系統相連,對區域溫度實現精確控制。

          動能平衡電動二通閥根據設計流量在工廠定制,與表準的房間溫控器連接,免調試。

          Combine the function of dynacing valves and electric adjusting valves. In variable flow rate system, the adjustment is fast and accurate.

          Structures compact,long cycle life,easy installation and energy-saving.

          Dynamic balancing electric valves are connected with building automation syetem and they work together to operate system united adjustment.

          Dyuamic balancing electric two-way valves are customized in factory in accordance with the desiging flow rate and are connected with temperature,adjustment free.

          產品特性 Features

          既有平衡及啟閉功能,溫度控制精確性高,在工作壓力差范圍內,流量始終保持不變,閥的啟閉只隨著房間的變化而變化,在系統壓力下波動較大的變流系統中保持精確的流量,關閉狀態穩定,關閉時間相對恒定,抗干擾能力強,要求維持最小壓差以保持動能平衡,適用于暖通空調風機盤管系統的溫度控制。

          With both balancing and modulating functions,High precision in temperayture control. Flow rate remains constant in the differential pressure range,Valve opening only changes with the chang the room temperature, Keeping precise flow rate in variable flow rate syatem, Steady open-condition, invariable open-close time, high anti-jamming capacity, Sustaining the lowest differential pressure to keep dynamic balance,applicable to the temperature control in fan coil unit of heating ventilating air-conditioning syatem.
