Honeywell PP901, PP902 Catalog Page
Pneumatic Pressure Controllers
PP901; PP902 Pressure Reducing Valves
Used to control the pressure of the air delivered to pneumatic
control systems. Models available for single-pressure systems or
two-pressure systems (Day/Night or Summer/Winter) requiring two
independently regulated pressure settings. Dual-pressure units
switch from the lower settings to the higher settings when main air
is applied to the pilot port. Models also available including a submicron filter assembly and pressure gauges. Replacement devices
are available for Johnson, Powers, Robertshaw, Barber-Colman
and older Honeywell pressure reducing valves.
• Built-in adjustable safety relief valve for limiting downstream
pressure.
• For two-pressure models: Pressure changes accomplished with
manual switch or automatically with electric pneumatic switch.
• Adjustable stops for desired settings.
