Product Details
SQD204
Top guided three-way regulating valve
Electric Linear Stroke Regulating Valve
Product overview
SQD204 type electronic three-way combined/split control valve is mainly used to divide a stream of inlet fluid into two streams of fluid or combine two streams of inlet fluid into one stream of outlet fluid. The three-way valve is divided into (SQD204Q) combined regulating valve and (SQD204X) split regulating valve. Valve size, when the pressure difference is small, the confluent valve can also be used as a diverter valve, but the valve size is large, the pressure difference is high, please do not use the diverter valve.
