Honeywell 14004898-001 Repair

The Honeywell 14004898-001 is a high-precision valve rebuild kit engineered specifically for VP531A and VP531C series pneumatic terminal unit valves. This OEM Honeywell secondary insert and repair top assembly features a 1.6 Cv rating, providing accurate modulation and equal percentage flow characteristics required for consistent climate control in commercial HVAC systems. Designed for field-service reliability, the 14004898-001 is a direct replacement for the 14004898-001/U, ensuring a seamless fit without the need for piping modifications when addressing leaking packing or failed internal components.

As a veteran-grade Honeywell valve repair part, this kit is vital for maintaining 1/2-inch NPT or solder-body VP531 valves without replacing the entire body. The assembly includes the stem, plug, and packing nut, allowing technicians to restore factory-spec performance to pneumatic heating valves. By replacing the internal top and insert, you ensure low-friction operation and prevent the bypassing that degrades system efficiency. This kit is purpose-built for technicians who prioritize OEM-level compatibility and the long-term integrity of pneumatic control loops.

• Ensures 1.6 Cv flow capacity to maintain precise temperature control in hydronic terminal units.
• Compatible with both VP531A pneumatic valves and VP531C series terminal unit valves.
• Includes the Honeywell valve insert and top assembly for a comprehensive internal overhaul.
• Maintains the normally-open failsafe position found in standard VP531 configurations.
• Direct interchangeability with the 14004898-001/U catalog number for simplified inventory management.

Can I use this kit to change the Cv rating of my current valve?
This kit is calibrated specifically for 1.6 Cv. While the 14004898 series offers different flow ratings, installing this 1.6 Cv insert into a valve body originally rated for a different capacity will change the flow characteristics of your loop. Always verify the design specs before switching Cv ratings.

Does this kit work with the V5011 or V5013 globe valves?
No, this specific repair top and insert is tailored to the VP531 series pneumatic valves. Globe valves typically require different stem and plug assemblies. For V5011 models, please reference our specific Honeywell rebuild kits for large-body valves.

Is the packing nut included with the assembly?
Yes, the 14004898-001 is a complete top and insert assembly that typically includes the stem, plug, and integrated packing components to resolve common vacuum or pressure leaks at the bonnet.
