Description
The 3-way control valve includes diverging and converging actions, it can replace two sets of the two-way valves and widely used on many occasions to regulate pressure, flow rate, temperature, and liquid level. Spool structure with side guiding, well stability, no vibration, low noise, can bear high-pressure difference, easy for connection, etc. While with low nominal size and pressure difference, a converging valve can be used in the diverging occasions. However, while the nominal size higher than DN100 and high-pressure difference, the converging valve, and diverging valve can’t be exchanged.
