Macon Controls N10657 Body

The Macon Controls N10657 is a heavy-duty vertical angle radiator valve body designed for precision flow control in hydrologic and low-pressure steam systems. Featuring a 3/4 inch NPT female inlet and a 3/4 inch male union outlet with a straight nipple, this forged brass, nickel-plated body is engineered for seamless integration with NT series thermostatic operators. With a 2.5 CV flow capacity, the N10657 excels in regulating hot water or steam in freestanding radiators, convectors, and baseboard units. The EPDM disc material ensures a positive seal at static pressures up to 145 PSI and temperatures reaching 250°F. For contractors, the replaceable insert design allows for maintenance without draining the entire system, significantly reducing labor time. This thermostatic radiator valve body facilitates automatic temperature modulation, balancing the heating system while minimizing expansion noises. The vertical angle orientation is specifically suited for specialized piping configurations where space and alignment are critical for professional HVACR valve installation.

Key Benefits for Contractors:

• High flow capacity: 2.5 CV rating ensures optimal heat distribution for standard and high-capacity radiation units.
• Dual-service compatibility: Engineered for both hot water and 15 PSIG low-pressure steam applications.
• System efficiency: Supports non-electric thermostatic control, leading to fuel savings and improved system balancing.
• Durable construction: Forged brass body with nickel plating provides superior corrosion resistance and longevity.
• Serviceable design: The internal valve insert and NT series operator can be replaced without a full system shutdown.

Common Questions:

What is the maximum operating pressure for the N10657?
This valve body is rated for a maximum static pressure of 145 PSI and a maximum steam pressure of 15 PSIG.

Does this valve body include the thermostatic head?
No, the N10657 is the valve body only. It must be paired with a Macon Controls NT series operator (such as the MTW, MOE, or MVA) for automatic temperature control.

Can this be used in one-pipe steam systems?
While typically used in two-pipe systems, the N10657 is often utilized in one-pipe steam applications when paired with the proper Macon Controls OPSK conversion kits for atmospheric venting.
