3501 Pneumatic Volume Regulator
This is in contrast to the 3011 PVR, which resets velocity pressure with a change in thermostat
pressure. This allows the 3501 PVR to have improved stability at low flows.

The 3501 PVR can be set to control either normally open or normally-closed
air valve actuators and can be calibrated to accept either direct-acting or
reverse-acting thermostat signals. Fixed reset control of maximum and
minimum airflow setpoints is provided. The controller is used primarily in
dual-duct constant-volume applications because of its linear output
response characteristics. The controller resets the primary air velocity
linearly with a change in thermostat pressure.
