Armstrong International D24677 Valve

The Armstrong International D24677 is a high-performance 3/4" Straight Pattern RV-4 Thermostatic Radiator Valve Body, specifically engineered for precision temperature control in low-pressure steam and hot water hydronic systems. This robust valve body includes the specialized "S" Insert, ensuring a reliable seal and responsive modulation for radiators and convectors. Serving as the direct replacement for 6005676, the D24677 valve allows facilities to maintain optimal heating efficiency without extensive repiping. Its nickel-plated brass construction provides superior resistance to mineral deposition and corrosion, making it a staple for commercial HVAC maintenance in schools, hotels, and industrial buildings. By integrating this thermostatic radiator valve (TRV), users achieve consistent zone heating, effectively eliminating the common issue of overheating in individual rooms. Whether you are performing a steam heating system repair or upgrading to a thermostatic control valve, the D24677 offers the mechanical durability and technical precision required for modern energy management.

• Universal Compatibility: Engineering as a direct replacement for 6005676 ensures a seamless fit for existing Armstrong radiator setups.
• Energy Efficiency: Precise modulation helps reduce energy waste by preventing room overheating in low-pressure steam systems.
• Durable Construction: Features a heavy-duty nickel-plated brass body rated for 15 PSI (steam) and 150 PSI (water).
• Versatile Application: Ideal for hydronic heating, radiators, and heat exchangers requiring a 3/4" straight pattern configuration.
• Precision Control: The integrated "S" Insert facilitates accurate temperature sensing when paired with a thermostatic operator.

• What is the maximum pressure rating for the D24677? This valve is rated for a maximum operating pressure of 15 PSI for steam and up to 150 PSI for water applications.
• Which part does the D24677 replace? It is the official manufacturer-designated direct replacement for the 6005676 valve body.
• Can this be used for one-pipe steam systems? While the RV-4 series is designed for low-pressure steam, always verify your specific system configuration (one-pipe vs. two-pipe) to ensure proper air venting and condensate return.
