Resideo VU53N1026 Valve

The Resideo VU53N1026 Valve is a professional-grade two-way fan coil valve engineered for high-pressure commercial HVAC applications, specifically within terminal reheat coils, convectors, and fan coil units. This 1" NPT fan coil valve features a robust brass body with a normally closed configuration, providing a flow capacity of 8 Cv and a maximum safe operating pressure of 300 psi. Designed for versatility, it manages chilled water or hot water systems with up to 60% glycol concentration. The internal assembly includes a brass stem, brass seat, and a triple O-ring seal with EPDM rubber packing to provide three lines of defense against drive shaft leakage. The patented ball seal design ensures a soft close-off while maintaining a 10 psi maximum close off pressure differential. This valve body is specifically designed for quick opening flow characteristics and is meant for use with VU443 and VU843 actuators.

• High Pressure Capability: Rated for up to 300 psi, making it suitable for high-rise commercial hydronic systems.
• Durable Construction: Features a corrosion-resistant brass body, stem, and seat for long-term reliability in demanding environments.
• Precise Seal Integrity: Utilizing a Buna-N rubber plug and EPDM rubber packing to prevent internal and external leaks.
• Installation Flexibility: Compact design fits easily under baseboard convector covers even when coupled with an actuator.
• System Compatibility: Standardized 1 inch NPT female threads allow for seamless integration with iron or steel piping.

Common Questions:

Can the Resideo VU53N1026 be used in domestic water systems?
