PART REQUEST FORM

Ensure proportional fluid distribution across all heating and cooling zones with calibrated Circuit Setters and hydronic balancing valves. Featuring genuine Bell & Gossett Circuit Setter Plus valves and essential boiler trim, our catalog provides HVAC contractors and technicians with precise flow measurement and throttling capability for commercial loops.

Calibrated Flow Control & Hydronic System Balancing

Unbalanced hydronic loops lead to uneven heating, noisy piping, and overworked circulator pumps. Installing a calibrated Circuit Setter at each branch or terminal unit allows technicians to measure differential pressure and lock in exact design GPM flow rates.

Key Features & Hydronic Trim Options

  • Integrated Pressure Readout Ports: Dual readout valves with integral check valves for quick connection to differential pressure gauges during system balancing.
  • Precision Metering & Memory Stop: Calibrated nameplates and adjustable memory stops allow valves to be closed for service and reopened to the exact setpoint without re-balancing.
  • Boiler Trim & Safety Valves: Complete pressure relief valves, pressure reducing valves, and gauge glass sets for commercial boiler installations.
