ZRHF (H) type electronic electric three-way control valve has two modes of action: electric three-way combined flow control valve and electric three-way split control valve, which can replace two two-way valves and a three-way valve in some occasions and are widely used. To realize the adjustment of pressure, flow, temperature, liquid level and other parameters, the valve core structure adopts a cylindrical thin-walled window, and adopts the side guidance of the valve core, which has the characteristics of good stability, not easy to produce vibration, low noise, large pressure difference allowed, and simple connection. When the nominal diameter and pressure difference are small, the combined flow valve can be used in the diversion occasion and can be used interchangeably, but the nominal diameter is greater than DN100 and the shunt occasion with a large pressure difference cannot be used interchangeably.
