DB450

Diaphragm back pressure regulators protect pneumatic devices
against overpressure. If the pressure exceeds the setpoint,
the pressure valve exhausts to the atmosphere until the
pressure level is below the setpoint. It is advisable to
select the pressure range as near as possible to the maximum
setpoint.

Media: compressed air or non-corrosive gases
Overpressure: max. 17 bar
Pilot pressure: 0 ... 10 bar
Accurcay: 3% at 7 bar pilot pressure
Response sensitivity: 2.5 mbar

Adjustment: depending on the level of signal pressure the response
value will change accordingly
