Resideo by Honeywell QVU8142A3231 N/O VU52 Fan Coil Valve Rebuild Kit 1/2"-1"

The Resideo QVU8142A3231 is a professional-grade rebuild kit designed to restore the functionality of normally open 1/2" to 1" VU52 Series fan coil valves. This service kit converts VU52 fan coil valves and their associated actuators to a Double-D stainless steel valve stem and brass sector gear for superior service life in closed hydronic systems using hot or chilled water with up to 60% glycol concentration.

Key Features:

• Upgraded Double-D 316 stainless steel driveshaft stem for enhanced durability
• Brass sector gear construction for superior service life
• Compatible with hot and chilled water systems with up to 50% glycol
• Humidity-resistant design suitable for condensing, non-corrosive environments
• Designed for systems with 300 psi operating pressure rating

This rebuild kit is used in conjunction with VU52 normally open fan coil valves for controlling the flow of hot or chilled water in commercial HVAC equipment such as fan coil units, terminal reheat coils, and convectors. The kit provides a cost-effective solution for extending valve service life without requiring complete valve replacement.
