Pressure regulator, MS4 Series

Features

The pressure regulator maintains a constant working pressure (secondary side), regardless of the pressure variations in the system (primary side) and the air consumption.
- Good regulation characteristics with low hysteresis and primary pressure compensation
- High flow rate with minimal pressure drop - Available with and without secondary venting
- Regulator lock for protecting the values against adjustment
- Four pressure regulation ranges: 0.3...4 bar, 0.3...7 bar, 0.5...12 bar and 0.5...16 bar
- Two pressure gauge connections for different fitting options
- Return flow option for exhausting from output 2 to output 1 already integrated
- Optional pressure sensor
- Optional rotary knob pressure gauge
- Optional device variant EX4 for use in potentially explosive areas in zones 1, 2, 21 and 22
