Product Overview LF690

INTRODUCING THE LF690...
The LF690 is a piston-sensed low-flow reducing regulator with ceramic seating to provide the ultimate protection against the harsh service encountered on water-based hydraulic applications such as water glycol. For hydro-carbon applications, refer to HYD691.

Its unique seating cartridge ensures the main valve is fully supported during operation to prevent ‘chattering’. The LF690 is supplied with a segregated captured vent to prevent deterioration to the loading mechanism and making the regulator easier to service.
