Overview
AQF valves limit pressure in oil lubrication systems after the relief setting is adjusted, protecting the system against pressure overload. Suitable oil viscosity grades are N22-N460. Small-bore valves, up to DN40, use an adjusting screw; larger DN50-DN100 valves use a handwheel.
Selection and operation
DN20–40 versions are adjusted by a screw; DN50–100 versions by a handwheel. The working-pressure range is determined by the model suffix.
