connection thread:	G3/8
connection:	G3/8
supply pressure max. [bar]:	17
pressure range [bar]:	0,07...4,0
overpressure max. [bar]:	17

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.
