CAT Pumps 7670 Quick Start Manual

FEATURES
Provides system pressure setting and protection
for single gun (non-weep) and pump installation.
Compact size with optional ports for easy
installation.
New ergonomic handle permits easy adjustments
of pressure.
Pressure sensitive feature permits wide range
of flows and immediate pressure when gun
opens.
Color coded spring for easy identification and
simple change from one model to another.
Also functions as a secondary Relief Valve
without the check valve.
Model 7691 has a quick start valve to relieve
pump discharge line pressure at start up.
WARNING
All systems require both a primary pressure regulating device (i.e., regulator, unloader) and
a secondary pressure safety relief device (i.e., pop-off valve, safety valve). Failure to
install such relief devices could result in personal injury or damage to the pump or to
system components. CAT PUMPS does not assume any liability or responsibility for the
operation of a customer's high pressure system.
