DESCRIPTION
The PP901A and B Pressure Reducing
Valves are used to control the pressure
of the air delivered to pneumatic control
systems.
The PP901A is used in single-pressure
systems, while the PP901B is designed
for use in two-pressure systems
requiring two independent regulated air
pressure settings.
