Technical details
Temperature range 0°C ... +50°C
Medium Filtered, oil-free and dried compressed air according to ISO
8573-1:2010, Class 7:2:4, instrument air, free of aggressive
additives. Alternatively the pressure dew point must be at
least 10°C below lowest occurring ambient temperature.
Materials Body: Al (anodized), plastic, seals: NBR, inner parts: Al, steel
and brass
With an increasing input signal, the solenoid valve SV1 (air supply) is switched ON while at the same time the solenoid valve SV2
(air exhaust) remains closed. Air is supplied to the pilot chamber. The pressure in the pilot chamber increases and is applied to the
upper side of the membrane. The valve which is connected to the membrane opens, and air flows towards the valve outlet.
The outlet pressure is monitored by a pressure sensor which transmits a corresponding electrical signal to the control circuit. The
control circuit adjusts the valve so that the outlet pressure is proportional to the input pressure.
The pressure sensor continually controls the outlet pressure and keeps it proportional to the inlet pressure.
