103 Series - High accuracy regulator

The 103 series utilises a rubber diaphragm, resulting in a very accurate control of outlet pressure.

A balanced main valve ensures a stable outlet pressure, even with a varying inlet pressure.  A rubber main valve seat offers very reliable bubble tight shut off at all operating pressures. 

A wide range of options are available, including materials to suit most medias, porting and gauge port options and a choice of handwheel or grub screw control. As with all of our regulators, bespoke solutions can be offered to suit most applications.  

These advantage make this regulator the perfect choice when a high accuracy and medium flow rate is required.
