Pressure limiter UB A2, NB A2 for Dungs multiple actuators
- These pressure switches ÜB A2, NB A2 are pressure limiters designed to work together with Dungs multiple actuators. If the set reference value is exceeded or undershot the system is locked and can be restarted only manually.
- It is suitable for switching a circuit on, off or over on changes in actual pressure value relative to the set reference value. The reference valve (switching point) can be set easily and quickly by means of a setting wheel provided with a scale without the use of a pressure gauge.
- They can be used together with multiple actuators GasMultiBloc MB and with DMV double solenoid valves. Various mounting options on housing or by means of an adapter.
- Maximum operating pressure: 500/600 mbar, setting ranges between 2.5÷500 mbar. Ambient and medium temperature -15÷70oC, storage temperature -30÷80oC.
- Switching voltage: DC: 12÷48 V, AC 10÷250 V. Nominal current: AC 10 A.
- The installation position can change the switching pressure with up to 0.5 mbar.
- Suitable for gases of families 1, 2, 3 and other neutral gaseous media.

Functional description:
Single-acting pressure switch in the overpressure range. The pressure limiters work without external energy supply. The switching mechanism reacts to superpressure. The system is locked if the set
reference value is exceeded or overshot. After the fault has been remedied, the system can be put into operation only manually by actuating the unlocking device on the pressure limiter. The switching state
"Locked" is indicated by a neon glow lamp.
- UB ... A2
Switches on and locks if the set pressure value is exceeded.
- NB ... A2
Switches on and locks if the pressure is lower than the set pressure value.
