Macon Controls N10777 Straight Body

The Macon Controls N10777 Straight Body is a professional-grade 1-inch thermostatic radiator valve designed for precision flow control in hydronic and low-pressure steam systems. This 1" straight body configuration features a 2.74 Cv rating, making it an ideal choice for high-capacity radiators, baseboards, and fan coil units where reliable temperature modulation is critical. Built with a forged, nickel-plated brass body and a stainless steel spindle, this valve is engineered to withstand operating temperatures up to 250°F and static pressures up to 145 PSI. Contractors prefer the Macon N10777 for its 1" FNPT x 1" MNPT union connection, which ensures a standard fit and simplified installation in existing pipework. The replaceable EPDM disc and insert allow for long-term field serviceability without necessitating a full valve replacement. Whether you are balancing a commercial two-pipe steam system or optimizing a residential hot water loop, this straight pattern radiator valve provides the durable mechanical interface required for localized zone control when paired with Macon NT series operators.

• Optimized Flow: High-capacity 2.74 Cv flow coefficient ensures sufficient volume for large heating units.
• System Versatility: Dual-application design is compatible with both hot water and low-pressure steam (up to 15 psig).
• Durable Construction: Nickel-plated forged brass body resistant to corrosion and mechanical stress in demanding boiler loops.
• Easy Maintenance: Features a replaceable insert and spindle, allowing for repairs without draining the entire hydronic circuit.
• Noise Reduction: Precision machining and high-quality internal components minimize expansion noises and water hammer effects.

Is the Macon N10777 compatible with one-pipe steam systems?
This straight-body valve is primarily designed for two-pipe steam and hydronic applications. For one-pipe steam systems, a specialized adapter assembly is typically required to ensure proper venting and condensate drainage.

Can I change the operator without shutting down the heating system?
Yes, the design allows for the thermostatic operator or actuator to be swapped or upgraded while the system is under pressure, minimizing downtime during service calls.

What is the maximum operating temperature for this valve?
The N10777 is rated for a maximum water temperature of 250°F, making it suitable for high-temperature hydronic cycles and standard low-pressure steam environments.
