Double stage pressure reducer – 1,5 bar - with membrane for nontoxic and non corrosive pure gases suitable for being

used with little pipeline system or connectedto single cylinders in analysis laboratories, gas

two regulators placed in cascade connection. Sincethis kind of regulator reduces the pressure

in two steps the delivery pressure (coming from thesecond regulator) is unaffected by changes of the

inlet pressure (i.e. cylinder pressure change) and is,therefore, more precisely controlled

SECOnd STAGE PRESSURE REdUCER

Pressure reducer for non toxic and noncorrosive pure gases. These reducers areideally suited for being used in analysis

laboratories, gas chromatography and massSpectrometry.

Pure gases outlets are automatic valves which placedalongside the piping allow the connection of second

stage pressure regulators 2nd stage to thepipeline system. They are offten used fixed on the wall or

on the laboratory desks allowing the use of gas indifferent places.

These outlets are available for both combustible and noncombustible gases.

RAMPS WITH SInGLE PURGE VALVE

Pure gases manifolds are ideally suited tocentralize pipeline systems for analysis laboratories andgas chromatography and they’ve been conceived for the

specific use with non corrosive pure gases.Any cylinder place is equipped with purge valve and

shut-off valve. These manifolds are available for 1, 2 and 3cylinder seats, for comburant, combustible gas; all of them are

mounted on a strongsteel support.

The decompression unit allows the use oftwo cylinders or two cylinder racks, when one of

the two gas sources is empty, the panel boardautomatically collects the gas from the other

source assuring the constant gas supplying. It ispossible to set the primary and the reserve

source by acting on the central setting lever.The couplings and the pipes are stainless steel

and all the brass parts are chromeplated.
