Summary
HDT300 series three-way regulating valve has two structures: HDT300X series three-way diverting type and HDT300Q series three-way converging type. The three-way diverting type is to divide one fluid into two fluids; the three-way converging type is to combine two fluids into one. ; Three-way regulating valve is often used for bypass regulating of heat exchangers, and can also be used for simple ratio regulating. This series of products can replace two single and double seat regulating valves that are on and off for each other, suitable for regulating and control of medium like liquid, gas, steam, etc.
This series of regulating valve can be easily made into special structures such as bellows sealing type, steam jacket type and extended upper bonnet.
