Pneumatic three way control valve is one type of regulating valve with pneumatic diaphragm actuator, which has two inlets or outlets. When one outlet is open, the other one will be closed, and then alternate. Three way regulating valve can be used as two phase regulation and simple proportion regulation. Sometimes, three way control valve can be used instead of 2pcs two way valve and 1pc three way pipe connector. Flowspec Luokai can manufacture and supply the pneumatic three way control valve according to standard of GB/T 12221-2005 with sizes of 3/4″ ~ 8″ (DN20~DN200mm). Contact us today.
