Product Details
SOD104
Three-way regulating valve
Pneumatic Linear Stroke Regulating Valve
Product overview
SQD104 type pneumatic diaphragm three-way control valve is mainly used to divide a stream of fluid into two streams of outlet fluid or to synthesize a stream of fluid into one stream of outlet fluid. The three-way valve is divided into (SQD104Q) combined regulating valve and (SQD104X) split regulating valve. Valve size, when the pressure difference is small, the valve flow can also be used as a diverter valve, but do not use a diverter valve when the valve size is large and the pressure difference is high.
