General description
The  uid pressure regulator is normally used in the painting systems to assure a good  uid
pressure control to the equipment. A regulator installed on a line reduces the pressure of
the main line until reaching the pressure required by this equipment.
The working principles of pressure regulators with manual control – referring to the
section of Fig. 1 and 2 – are as follows:
Fig. 1 (T090.00A, B, C, CR, MAG) Fig. 2 (T092.00AI, BI)
