进口动态压差平衡阀 动态差压控制阀 美国RETZ瑞茨

　　品牌：RETZ瑞茨/我们一直致力于流体控制和测控领域的持续创新，始于2005……

　　进口动态压差平衡阀外在高压端测压头带有锁闭阀，低压腔体导压孔内置，避免了现场安装的磕碰。广泛应用于恒定空调或供热系统中控制阀、末端设备或管网之路供水之间的压差，避免管网压差变化对其动态干扰，实现动态水力平衡retz The dynamic differential pressure balance valve is equippedwith a locking valve on the high-pressure end of the external pressuremeasuring head, and the low-pressure chamber has a built-in pressure guide holeto avoid collisions during on-site installation. It is widely used in constantair conditioning or Hydronics to control the pressure difference betweencontrol valves, terminal equipment or water supply on the way of pipe network,so as to avoid the dynamic interference of pipe network pressure differencechanges and achieve dynamic hydraulic balance
