Nibco F-737-A-212 Balancing Valve 2.5 in Ansi Flanged

Product Description

The NIBCO F-737-A-212 is an iron globe style balancing valve designed for HVAC and hydronic plumbing systems where precise flow control is required. This FLO-BOSS 737 series valve features a non-rising stem, an integral memory stop to retain flow settings, and an EPDM-coated disc for positive shutoff. Extended test points provide accessible measurement ports without removing the valve from the line. At 2.5 inches with ANSI flanged end connections, this valve suits commercial mechanical systems that demand repeatable, verifiable balance across multiple circuits.

This valve is used in commercial and industrial HVAC hydronic systems, including chilled water, hot water heating, and condenser water circuits. It is suited for applications where maintaining correct flow distribution across parallel circuits is critical to system efficiency and occupant comfort. Mechanical contractors and pipefitters install this valve during new construction and retrofit work on balanced hydronic systems.

Key Features

• Globe valve body style in iron construction for durable service in mechanical piping systems
• Non-rising stem design conserves clearance in tight mechanical room installations
• Integral memory stop retains calibrated flow settings after shutoff and reopening
• EPDM-coated disc provides positive shutoff capability
• Extended test points allow pressure and flow measurement without line interruption
• ANSI flanged end connections at 2.5 inches for direct bolt-up to flanged piping

Compatibility

Designed as an OEM-style balancing valve for commercial HVAC hydronic and plumbing piping systems requiring ANSI flanged connections at the 2.5-inch pipe size.

Installation Notes

Installation should be performed by a licensed pipefitter or mechanical contractor in accordance with applicable mechanical and plumbing codes. Isolate and depressurize the system before installing or servicing this valve. Flange bolts should be tightened evenly in a cross pattern to achieve proper gasket seating without over-stressing the valve body. Consult the NIBCO technical data sheet for recommended flow direction, pressure ratings, and fluid temperature limits before commissioning.
