Cylinder Pressure Regulator

The cylinder pressure regulators from the series FL are equipped with 1 / 2 or 3 measurement tubes.

It reduces cylinder pressure of compressed gases from a max. of 200 bar down to the outlet flow shown on the flowmeter measurement tube.

The integrated balanced poppet ensures a constant and uniform pressure throughout the emptying of the cylinder.

The exact amount of flow in l/min can be preset and read on the flowmeter measurement tubes.

The pressure regulator is fitted as standard with gas specific connections to DIN 477. A relief valve is also fitted.

The pressure regulator can be supplied as 1, 2 or 3x flowmeter with different measuring ranges.
