What is the minimum and maximum PSI applied to a 4800 operator?

The pneumatic operators are designed to function with an input air pressure to the 7901/7902 Series control box of 80 (min) 100 (max) PSI, and an output pressure of 60 to 80 PSI to the pneumatic (2610/4810/4820/4840) closer.

  • The control box regulators have a maximum pressure setting of about 85-90 PSI.
  • All the pneumatic closer have a built in pressure relief valve set at 100 PSI.
  • The pneumatic 925 tubing has a burst rating of 300 PSI.
