1、 Introduction to ZRHF Electric Three way Regulating Valve
ZRHF (H) typeElectric three-way regulating valveThere are two ways of operation: merging and diverging, which can be widely used in some situations as a substitute for two two-way valves and one three-way valve connection. Realize the adjustment of parameters such as pressure, flow rate, temperature, and liquid level. The valve core structure adopts a cylindrical thin-walled window and is guided by the side of the valve core. It has the characteristics of good stability, low vibration, low noise, large allowable pressure difference, and simple connection. When the nominal diameter and pressure difference are small, the merging valve can be used for diversion situations and can be interchanged. However, when the nominal diameter is greater than DN100 and the pressure difference is large, it cannot be interchanged.
