Installation Considerations
Bell & Gossett Circuit Setters are bi-directional and can be installed in various positions. However, they should be positioned to facilitate easy system balancing and optimal performance.
3.1 Pre-Installation Checks
Before installing a Bell & Gossett Circuit Setter, ensure all components are undamaged and compatible with the system. Verify that the valve is suitable for the intended application, whether it’s for HVAC or potable water systems. Check that the valve size matches the pipe diameter and that all connections are free from debris. Ensure the readout ports are properly sealed with the provided thread sealant, such as Loctite 567, to prevent leaks. Additionally, confirm that the Circuit Setter is configured correctly for bi-directional flow, as it can be installed in various positions. Review the system specifications to ensure the valve’s flow range meets the requirements. Finally, refer to the installation manual for any specific pre-installation steps or recommendations.
3.2 Positioning and Thread Preparation
Proper positioning and thread preparation are crucial for the Bell & Gossett Circuit Setter installation. The valve can be installed in most positions due to its bi-directional design, but it should be oriented to facilitate easy balancing of the system. Ensure the metering ports are not pointing downward to avoid potential issues with flow measurement. Before installation, inspect the valve’s threads for any debris or damage. Apply a compatible thread sealant, such as Loctite 567, to ensure a leak-tight connection. Avoid over-tightening, as this could damage the valve or system components. Align the valve with the system’s flow direction to maintain optimal performance. Proper thread preparation and positioning ensure accurate flow measurement and efficient system operation, aligning with the Circuit Setter’s precision engineering.
