3 Way Pressure Regulating Control Valve Feature
3 Way Pressure Regulating Control Valve is for diverting or converging service ,diverging structure to diverge one way flow fluid into two way fluid ,converging structure to converge two way flow fluid into one way fuild.3 Way Pressure Regulating Control Valve has diverging and converging structure for mixing and diverting service,3 Way Pressure Regulating Control Valve adopts double valve cores up and down guide structure, equipped with multiple spring actuator.3 Way Pressure Regulating Control Valve can replace two sets two-way valve and widely used in many occasions to regulate pressure, flow rate, temperature and liquid level.
