Dyna-Flo PRO-50 pressure regulator

Instrument supply pressure regulator, outlet 0 to 125 psig, inlet to 250 psi, −93 °C to +399 °C, for supply air and gas to actuators and positioners.

Every pneumatic actuator needs a clean, stable supply pressure. The PRO-50 is Dyna-Flo’s supply regulator, available in three outlet ranges up to 125 psig and rated for inlet pressures to 250 psi, so it can also be used on fuel gas supply at wellsites. It is normally mounted on the actuator yoke with a gauge and filter.

Selection data we need

Medium and its properties, inlet and outlet pressure, flow rate at minimum, normal and maximum conditions, temperature, allowable noise level, required shutoff class, pipe size and rating, actuator air supply and control signal, and any fail position. We size the valve and actuator in Dyna-Flo’s FloSpec software.

Applications

  • Instrument air supply to positioners
  • Supply gas regulation on wellsites
  • Pilot and controller supply
