品牌：RETZ/我们一直致力于流体控制和测控领域的持续创新，始于2005……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 equipped with a locking valve on the high-pressure end of the external pressure measuring head, and the low-pressure chamber has a built-in pressure guide hole to avoid collisions during on-site installation. It is widely used in constant air conditioning or Hydronics to control the pressure difference between control valves, terminal equipment or water supply on the way of pipe network, so as to avoid the dynamic interference of pipe network pressure difference changes and achieve dynamic hydraulic balance
进口动态压差平衡阀技术参数 Technical paramete
进口动态压差平衡阀采用平衡膜片和弹簧均为内置设计，自动恒定压差的的平衡阀，通过手动旋钮即可设定目标压差值，使用内六角扳手旋转可实现手动关闭功能 RETZ The imported dynamic differential pressure balance valve adopts the built-in design of the balance diaphragm and spring. For the balance valve with automatic constant differential pressure, the target differential pressure can be set through the manual knob, and the function of manual closing can be realized by rotating the hexagonal wrench
