Additional use:
¡ box pressure regulation
¡ pressure gas for electro pneumatic valves and pneumatic
drives
¡ for purge and fill of the system with desired inert working gas
when commissioning for the first time and after servicing and
repair.
Gas type Nitrogen, argon, helium or CDA (reactor may not filter O
2
)

5.0 bar ... 6.0 bar (0.5 ... 0.6 MPa) at connection point (second-
ary)
Flow rate 250 l/min
Connection type Ø 10 mm cutting ring screw
Overpressure safety relief valve
Connection equipment provided by the operating company: pressure relief valve for work-
ing gas.
Use Safety valve to prevent overpressure
Pressure Adjusted to 0.8 MPa (8bar) secondary site
