DESCRIPTION :

Cylinder regulator type RBNa/Nd-2,5R is single stage, leverless regulator which allows to decrease pressure of gases taken directly from the cylinder to constant outlet (working) pressure, set by the producer. The regulator is equipped with a gas flow rotameter scaled in dm3/min in two scales which allows the measurement of gas flow at the regulator outlet. This regulator has an outlet valve with a nozzle for a rubber hose with an internal diameter of Ø=4 or Ø=6. 3 mm, which allows for setting the required gas flow. The regulator is equipped with a safety valve through which the excess gas is released from the low pressure chamber when the outlet pressure rises above the permissible level (2. 5 bar). The maximum inlet pressure of the regulator is marked with a red line on the pressure gauge.

APPLICATION:

Cylinder regulator type RBNa/Nd-2,5R is used mainly for welding works e. g. welding in protective gas shielding: carbon dioxide and argon.

THE COMPOSITION OF THE SET
The regulator set includes:
 – regulator 1 pc.
 – spare gasket (ring) 2 pcs.
 – packing: cardboard box 1 pc.
