part number:	DB26-04G
connection thread:	1/2"NPT
connection:	1/2"NPT
pressure range [bar]:	14...690
Kv [m³/h]:	0,1
overpressure max. [bar]:	690

The back pressure regulator is a high-precison piston-operated regulator and 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.
