Gritton & Associates is a manufacturers representative for the residential, commercial and industrial markets. Our expertise and product lines are focused on HVAC, plumbing and steam systems.
Bell & Gossett has been the leader in hydronic balancing & flow control for over 60 years. We provide products and system solutions that make the engineer’s job easier, save money, and reduce time to install and commission the system. We offer a complete array of balancing & flow control solutions to fulfill all your needs, including: pressure independent control valves, automatic balancing valves, manual balancing valves and coil hook-up kits
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.
Save Energy, Save Time, Increase Comfort
Reduces energy costs and ensures better comfort
Reduces design, installation, and commissioning time
Multi Function: Adjustable Automatic Balance Valve & Full Modulating Control Valve
Maintains the set flow rate within +/- 5%
Integrated Pressure/Temperature Ports to easily measure differential pressure and temperature
Watch Video to see how the Optiflo Valve provides hydronic balance for ultimate system efficiency
Externally adjustable flow limiter that provides hydronic balance for ultimate system efficiency
Maintains the set flow rate within +/- 5% regardless of pressure fluctuations in the system as long as the ΔP across the valve falls within the allowable range
External, lockable, handle allows for easy adjustment of flow should design specifications change
Integrated pressure / temperature ports to easily measure differential pressure and temperature
No minimum straight pipe lengths required before or after the valve
Calibrated automatic flow limiting valve with a precision machined ball type shutoff valve, and commissioning measurement ports. The valve is designed for flow limiting-style balancing of both HVAC cooling and heating circuits; the valve is not for use in potable water systems. The use of the flow cartridge facilitates easy flushing of the piping upon commissioning the system.
A balance valve, a flow meter, a drip tight service valve. Designed, manufactured and tested to provide cost savings advantages of pre-set proportional balance. This system balance method, developed by Bell & Gossett, assures optimum system flow balance at minimum operating horse power.
Coil Hook-Up Kits
Bell & Gossett offers 16 standard valve installation kits, with options for flexible braided metal hoses, and pipe run out sizes from 1/2″ to 2″ in size, allowing for hundreds of installation combinations.
