Danfoss 065F0104 Thermo Valve

The Danfoss 065F0104 VMT series is a heavy-duty 2-way seated valve engineered for precise flow control in hydronic heating and cooling systems. Built with a rugged brass body for long-term reliability in demanding commercial and residential environments, this 3/4 inch valve features a 2.7 Cv flow capacity and a linear flow characteristic to ensure stable thermal regulation. It is specifically designed to manage the distribution of hot water or glycolic solutions in applications such as floor heating systems, plate heat exchangers, chilled coils, and hot water storage tanks.

For automated temperature management, the 065F0104 is fully compatible with Danfoss RAVK and RAVV self-acting thermostatic actuators, as well as TWA-V or ABV thermo-hydraulic actuators (24VAC). The unit includes a 3/4 inch double solder union connection, rated for a maximum working pressure of 145 psi (10 bar) and fluid temperatures up to 248°F (120°C). Technicians should note the cast-in flow arrow on the brass housing to ensure proper orientation and prevent system noise or cavitation during operation.

• High Temperature Tolerance: Rated for media temperatures from 35°F up to 248°F, making it suitable for both heating and cooling loops.
• Actuator Versatility: Seamlessly integrates with Danfoss VMT components, including electric thermal wax actuators and self-acting sensors.
• Durable Construction: Features an NBR rubber valve cone and a CrMo steel stem to withstand repetitive cycling and district heating circulation.
• Linear Control: Provides predictable flow modulation for accurate HVAC zoning and energy efficiency.

• Can this valve be used with glycol? Yes, the Danfoss 065F0104 is rated for water and glycolic water mixtures up to 30%.
• Which actuators are compatible with the VMT 20/8? This 3/4" valve is designed for use with Danfoss TWA-V, ABV, RAVI, RAVK, and RAVV series operators.
• Is the packing gland replaceable? Yes, the design allows for the packing gland to be serviced or replaced without removing the entire valve body from the line.
