Honeywell PP901 Pressure Reducing 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
