Air/Gas ratio regulators RAG

The regulators are made of aluminium alloy die-cast, with a range for inlet/outlet connections from 3/4” up to 2”.

Gas inlet pressure up to 500 mbar, air control pressure up to 120 mbar.

They are equipped with an adjustable spring and a counter spring, so that gas outlet pressure is equal to air control pressure, with a ratio 1:1 and an adjustable offset of +/-3mbar. The offset is useful to set gas flow at low fire.

RAG regulators have been designed for a flow regulation range equal to 10:1 and to generate low pressure drop.

Disc is equipped with a gasket, so RAG is able to regulate precisely very low flow.

Every model is equipped with a bypass adjustable on-site. Bypass is useful in low fire state when a very low flow is necessary or air control pressure is lower 0.5mbar.

The controls are equipped with inlet pressure compensation diaphragm for a precise regulation.

A metallic mesh filter protects the regulator seat from dirt contamination (filtration grade <1mm).

The impulse line is integrated inside the regulator. Special versions with external impulse line are available on request.
