INTRODUCING THE
HYD691...

The HYD691 is a low-flow hydraulic pressure regulator. Specifically targetting
mineral oil applications, it has been designed as a compact and economical
alternative to our LF690, yet still incorporates all of its key features
including a ceramic seat. In comparison, the LF690 offers more extensive Cv
options and caters for the harsh services encountered on water-based hydraulic
applications such as water glycol.



Its ceramic ball has a ‘glass-like’ finish to provide a positive shut-off and
is also fully supported to ensure fixed travel in the ‘Y’ axis. The HYD691 is
self-relieving with a segregated captured vent as standard.
