KV210系列螺纹电动动态平衡两通阀
Series Dynamic Balancing Electric Two-way Valves

电动动态平衡调节阀 Dynamic Balancing Electric Valves

概述 Description

保证系统压力变化过程中二通阀流量确定不变,使二通阀和末端盘管曲线形成良好的线性,使阀的开度与能量的调节形成很好的对应关系得到快速准确的控制,使系统的供热或制冷达到最良好的运行效果。

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 特点 Features

集动态流量平衡阀及电动二通阀的功能为一体,在变流量系统中,调节快速准确,结构紧凑,使用寿命长,安装简便,减少能源消耗。

动能平衡电动二通阀与室内温控系统相连,对区域温度实现精确控制。

动能平衡电动二通阀根据设计流量在工厂定制,与表准的房间温控器连接,免调试。

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.


l 产品特性 Features

既有平衡及启闭功能,温度控制精确性高,在工作压力差范围内,流量始终保持不变,阀的启闭只随着房间的变化而变化,在系统压力下波动较大的变流系统中保持精确的流量,关闭状态稳定,关闭时间相对恒定,抗干扰能力强,要求维持最小压差以保持动能平衡,适用于暖通空调风机盘管系统的温度控制。

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.
