What is it?
The Bell & Gossett OPTIFLO™ pressure independent temperature control and balancing valve (PICV).

The OPTIFLO™ combines an externally adjustable automatic balancing valve and a full modulating control valve.

This provides modulating control with full authority regardless of any fluctuations in the differential pressure of the system, meaning less design and installation times, better energy efficiency and more comfort to the end-user.

Typical application
• Commercial HVAC
Selection Process
Easy Valve Selection
• Simply determine the flow rate of the coil, or load of the system,
• select the pipe size, and
• make the selection.

Our charts make calculating minimum differential pressure a breeze. Whether you’re at the minimum differential pressure required, or at maximum, you will be within +/- 5% of the flow that the valve is set for.
In addition, there’s no need to select a separate automatic temperature control valve – it’s included as an all-in-one solution.
