Macon Controls N10757 Valve Body

Engineered for high-demand hydronic and low-pressure steam applications, the Macon Controls N10757 is a 3/4-inch straight pattern thermostatic radiator valve body featuring a 2.5 Cv flow coefficient. This forged brass, nickel-plated body is built to withstand rigorous commercial and industrial environments, providing reliable service for freestanding radiators, convectors, and baseboard units. Designed as part of a modulating system, it interfaces seamlessly with Macon non-electric thermostatic operators to deliver precise individual room temperature control without the need for external wiring or electricity. Its compact Footprint and FNPT x MNPT union connection simplify HVAC valve body installation in tight mechanical spaces. The stainless steel spindle and replaceable insert ensure long-term performance stability under standard operating pressures—up to 15 psig for steam and 125 psig for water systems. This industrial flow control valve helps eliminate expansion noise and optimize fuel consumption by preventing over-heating in zoned heating loops.

• Optimized Flow Control: The 2.5 Cv rating provides precise modulation for hot water and low-pressure steam systems.
• Durable Brass Construction: Forged, nickel-plated finish resists corrosion and ensures structural integrity in high-temperature environments.
• No Electricity Required: Functions as a fully automatic modulating unit when paired with Macon self-acting operators.
• Field-Serviceable Design: Features a replaceable valve insert, allowing for maintenance without disturbing the piping.
• Versatile Compatibility: Standard 3/4" NPT threaded inlet and union outlet fit most residential and commercial hydronic radiators.

Is the Macon N10757 compatible with steam systems?
Yes, this valve body is specifically rated for low-pressure steam systems up to 15 psi WSP, as well as hot water applications up to 125 psi WOG.

Can I change the thermostatic operator without draining the system?
Yes, the Macon N10757 allows for the operator to be replaced or swapped without the need to drain or isolate the heating loop, minimizing downtime during service.

Does this valve require a specific mounting orientation?
While the straight body pattern allows for flexible installation, the flow must follow the arrow marked on the forged body for correct modulation and to avoid water hammer.
