The LF690 pressure regulator incorporates metal to metal seating to withstand the harsh service encountered in hydraulic pressure control. The unique seating cartridge provides a dampening action to the main valve to prevent ‘chattering’ or ‘unstable frequency resonance’. The regulator is self-relieving as standard, with segregated captured venting to prevent deterioration to the loading mechanism and making the regulator cleaner to service. The seating area can be easily accessed from the bottom of the regulator for speedy servicing in situ.
