Description
The Browning 1VP71X Variable Pitch Sheave is an essential for managing the speed of the HVAC System motors and fans. The variable pitch design enables fine and continuous changes which enhance system performance under different operating conditions. The sheave is composed of two parts, a fixed part and a sliding part. The movable half can be moved axially, this has the effect of altering the pitch diameter of the sheave. This variation in pitch diameter has a direct bearing on the speed of the driven component which would be the motor or the fan if connected with a belt drive.
