FACTORY SETTINGS FOR A STANDARD VALVE
- 0 bar outlet pressure at a setpoint of 0 V / 0 mA / 4 mA.
- Span: 3 bar device: = 3 bar at 10 V / 20 mA
6 bar device: = 6 bar at 10 V / 20 mA
10 bar device: = 10 bar at 10 V / 20 mA
- Minimum hysteresis.
- The control parameters, setpoint offset, setpoint span and window size of the digital output (pressure switch)
are factory-programmed.
Parameter set: factory settings
Setpoint offset: 0 %
Setpoint span: 100 %
Setpoint ramp: no ramp
Shut-off: ON; the valve is exhausted at a setpoint below 0.5%
Controller structure: PID
Proportional gain: 4,0
Integration time: 0.1 sec
Derivation time: 8 msec

PNEUMATIC CONNECTION
The air flow is from port 1 to port 2.
Inch screw connections (pipe threads) must be used.
Each screw connections must be lined with a fitting synthetic sealing disc.
Do not use Teflon sealing tape or hemp as they may get inside the valve and damage it.
Use an appropriate silencer at port (3). The exhaust time may vary depending on the type of silencer used.
The diameter of the pneumatic lines must be adjusted to the nominal diameter of the valve. The diameter of outlet
line (2) must be larger or equal to that of inlet line (1).
The supply pressure must always be less than the value given in the table in section 3 and must always be above
the desired outlet pressure.
