Based on the same design features of the LF-690 Hydraulic
Regulator, the LF-692 incorporates a PEEK seat for use on
high pressure gases, using a range of precision machined
sensing elements to provide control of pressure to 690bar.
The regulator is self relieving with segregated captured
vent to allow vented gases to be piped away to a safe area.
The seating area can easily be accessed from the base of
the regulator for speedy servicing in situ.
