JUAL MB-ZRDLE 410 B01 S50 | DUNGS Gas Multi Block

Technical description


Gas MultiBloc MB-ZRDLE 410 B01 S20 Dungs
regulator, valves and pressure switches in
one compact fitting.
– Dirt trap: Fine-mesh sieve
– One regulator and two main valves:
– Oneone-stage valveandonetwo-stage
– One valve is fast opening, one valve is
slow or fast opening
– Solenoidvalvesupto360mbar(36kPa)
as per DIN EN 161 Class A Group 2
– Sensitive setting of output pressure by
proportional regulator as per DIN EN 88
Class A Group2
– High flow rates with low pressure drop
– DCsolenoiddriveinterferencedegreeN
– Main volume restrictor and partial volume restrictor at valveV2
– Hydraulic openingdelay
– Flangeconnectionswithpipethreadsas
per ISO 7/1
– Simple mounting, compact, light-weight
The modular system permits individual
solutions by using external ignition gas tap
in connection with separately controlled
valves, by adding a valve proving system,
mini/maxipressureswitches,pressurelimiters, limit switch and closing stroke limiter at
valve V2, regulator blocking for liquid gas
The modular system permits individual
solutions in gas safety and regulator engineering. Suitable for gases of families 1, 2,
3 and other neutral gaseous media.
