Honeywell 310137 Packing Spacer

The Honeywell 310137 Packing Spacer is a critical internal component engineered specifically for VP513 and VP517 Series pneumatic valves. In high-pressure water and steam applications, maintaining a leak-proof seal at the valve stem is essential for system stability. This OEM Honeywell part functions by providing the necessary compression and alignment for the packing cartridges, ensuring that the pneumatic actuator can modulate the stem without premature wear or friction-induced failure. During a valve repack or assembly, professional technicians must note that two packing spacers are required per valve body to meet original equipment specifications. The 310137 is technically identical to the 310137/U universal designation, offering a direct drop-in replacement for worn spacers in commercial HVACR systems. Utilizing genuine replacement valve parts maintains the tight sealing and efficient flow control required for precise hydronic balancing and pressure management in single-seated water valves.

• Direct Compatibility: Specifically designed for seamless integration with Honeywell VP513A, VP513B, and VP517 series valve bodies.
• Precision Alignment: Facilitates proper stem packing compression to prevent localized leaks and reduce mechanical stress on the actuator.
• Interchangeable Design: Full functional equivalence between 310137 and 310137/U ensures ease of sourcing for critical repairs.
• Durable Construction: Built to withstand the thermal and chemical demands typical of industrial valve assemblies and high-temperature water loops.

How many spacers are needed for a complete valve service?
Standard service for VP513 and VP517 valves requires two spacers per valve. It is standard practice to replace both simultaneously to ensure uniform pressure across the packing rings.

Can I use the 310137/U if my manual lists the 310137?
Yes, these parts are physically and technically identical. The "/U" suffix denotes a universal SKU for distribution purposes, but the dimensions and material specifications remain the same.

Is this spacer compatible with other Honeywell pneumatic valves?
This part is specifically validated for the VP513 and VP517 series. For other pneumatic or electronic valve series, please consult the specific valve rebuild kit documentation to ensure proper fitment.
