REGAL 3 Spring-Loaded Regulator, Balanced Plug

The REGAL 3 is a direct-operated, spring set point pressure regulator, used for supplying industries and commercial businesses.

As an option, it can be equipped with a slam-shut Type VSX2 or OS2 which permits the gas flow to be cut off rapidly and totally in the case of under or over outlet pressure.

As a standard feature for outlet pressure settings inferior or equal to 180 mbar, a relief valve is provided.

The REGAL 3 is in conformity with the Pressure Equipment Directive PED 97/23/EC and is classified in Category I
