An additional pressure gauge indicates the available network pressure. Area of application The pressure regulators PR-A3 / PR-A4 are used in combination with pneu­ matic springs (e.g. SLM type) for setting the required pressure in each regu- lator circuit. Pressure losses through leakages are automatically compen­ sated. For use at constant load distribution. Mode of operation By using the pressure regulators, the network pressure is reduced to such an extent that the connected pneu­ matic spring elements carry the applied load. Please observe the assembly instructions of pneumatic spring elements!
