Did you know?

A regulator without relief can only correct upwards. Lower the setpoint and the pressure stays put until air is used, which skews measurement rigs.

Service units and instrumentation

Pneumatic pressure regulators maintain downstream working pressure within ±0.1 bar across inlet ranges from 0.2 to 25 bar, with precision regulators achieving set-point repeatability of <0.05 bar - critical for sensitive assembly, test, and process applications. Maintenance units combining filter, regulator, and lubricator (FRL) comply with ISO 4414 and DIN EN 983, offering filtration grades from 5 µm (standard) down to 0.01 µm (sterile-grade), flow capacities up to 5 000 Nl/min, and port sizes from G 1/8 to G 2. Safety valves in this range are certified to PED 2014/68/EU and carry CE marking for operating pressures up to 16 bar.
