Resideo VU52S2028 Valve

The Resideo VU52S2028 is a high-performance two-way fan coil valve engineered for precise control of hot or chilled water in commercial and residential HVAC applications. This normally open valve features a 1/2-inch sweat connection and a 3.5 Cv flow coefficient, making it an ideal choice for terminal reheat coils, convectors, and fan coil units. Built with a rugged brass body, stem, and seat, the unit utilizes a Buna-N rubber ball plug and EPDM rubber packing to ensure a reliable seal and long-term durability in closed-loop systems. Designed for quick opening flow characteristics, it manages differential pressures up to 20 psi and is compatible with up to 60% glycol solutions. This valve body is specifically designed for seamless integration with VU444 and VU844 actuators, allowing for efficient field replacement or new installations without disrupting system piping.

• High Close-Off Reliability: Features a patented ball seal and triple O-ring protection to prevent leakage and ensure a 20 psi maximum close-off rating.
• Durable Material Construction: The forged brass body and stainless steel drive shaft provide resistance to corrosion and mechanical wear in demanding hydronic environments.
• Streamlined Installation: Compact design fits easily under the covers of most baseboard convectors, saving time in tight mechanical spaces.
• Maintenance Efficiency: Compatible actuators can be removed or serviced with a single button press, eliminating the need to drain the system.
• Versatile Media Compatibility: Rated for a wide temperature range (34°F to 125°F ambient at 200°F fluid) and high glycol concentrations.

Is the Resideo VU52S2028 suitable for steam systems?
This specific model is designed for chilled or hot water applications. For low-pressure steam requirements, ensure your system parameters do not exceed 15 psi and utilize a compatible Class F motor actuator.

What actuators are compatible with this 1/2" sweat valve?
The VU52S2028 is a normally open (N.O.) body. It is designed to work with VU444 (line voltage) or VU844 (24V) series actuators to provide two-position control.

Can this valve be used in open potable water systems?
No, these valves are intended for closed-loop hydronic systems and should not be used in systems containing dissolved oxygen or for potable water service.
