KV2101F法兰系列电动动态平衡调节阀
Series Dynamic Balancing Electric Modulating Valves

l         产品特性 Features

既有平衡及比例积分调节功能,在很小负荷到满负荷的所有控制范围内稳定调节,自动保持所调流量的恒定,实现电动调节与动能平衡同步执行,确保一体阀的精确调节控制。开闭状态稳定,抗干扰能力强,减少电动执行器的动作次数,延长阀门使用寿命,要求维持最小的压差以保持动能平衡,适用与变水量系统,组合式空调,暖通空调系统,及与DDC连接控制。

With balancing and proportional-integral control function,Modulating from low load to fuii load Automatically keeping the modulated flow rate unchanged. The electric modulating valves and dynamic balacing valves operate synchronously, steady open-close condition high anti-jamming capacity, decreasing operating times of electric actuator and prolonging its service life,minimum differential pressure has to be sustained to keep dynamic balance,applicable to variable flow rate system, combined air-conditioning. Heating ventilating air-conditioning system and connecting control with DDC.
