INTRODUCING THE LF-690...
The LF-690 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 HYD-691.
Its unique seating cartridge ensures the main valve is fully supported during operation to prevent ‘chattering’. The LF-690 is supplied with a segregated captured vent to prevent deterioration to the loading mechanism and making the regulator cleaner to service.
APPLICATIONS: • Wellhead logic and control systems • Subsea valve actuator control • Valve test rigs • Liquid sampling • Hydraulic Power Packs
