厂家供应动态平衡阀 PRE AR-I 质量保证

在一定压差范围内维持管道水系统的流量平衡，在工作压差范围内精确控制管路流量。使系统时刻保持平衡，*人工调节。每台阀门在出厂时已设定流量，主要由其阀芯决定。

PRE AR-I series dynamic flow balancing valve regulates flow when the system pressure fluctuates in the operating differential pressure range, it can keep the pipe flow constant by dynamically balancing the change of pressure.
Its automatic operation completely depends on system differential pressure, maintaining the system flow constantly. The flux is set before delivery, and it is controlled by the core.


特点：
在工作压差范围内可准确控制管路流体流量，使整个系统时刻保持平衡，不会因为某一区域流量的变化而影响整个系统流量的稳定。
能够有效防止流量过大而造成设备的损坏，提高设备的使用寿命和安全性。
对如水泵、末端空气处理机组、制冷主机选型时能有效控制其富余容量，达到降低投资、降低能耗的目的。
Accurately regulates the flow of every branch when the system pressure fluctuates in the operating differential pressure range.
It won’t be changed due to any single branch flux, which ensures the flux stability of the entire system.
Avoid any damage occurs due to excess flow, and then ensure the lifespan and security of the valve.
It can cut down cost and consumption by controlling the excess flow to in water pump, terminal air handling unit, air-conditioner, etc.
