Nor East Controls 30753373-001 Bonnet Assembly

The Nor East Controls 30753373-001 Bonnet Assembly is a specialized replacement component engineered for use with 3-inch V5011A globe valves. Designed for high-demand HVACR applications, this replacement bonnet assembly ensures a secure seal and stable housing for the valve stem and packing, maintaining system integrity in chilled water, hot water, and low-pressure steam systems. Built for heavy-duty HVAC valve maintenance, the assembly supports the precise modulation required in single-seated, straight-through valve bodies.

Constructed to meet OEM specifications, this 3" V5011A bonnet features compatibility with spring-loaded PTFE packing to minimize friction and prevent stem leakage. As a veteran in the field knows, a direct-fit bonnet assembly is critical for ensuring the V5011A valve restoration project maintains its 125 lb ANSI pressure rating. This part provides the necessary structure to seat the actuator firmly, whether using pneumatic or electric-electronic linkages, ensuring the 3/4-inch stem travel remains consistent under load.

Key Benefits:

• Specifically engineered for 3" V5011A flanged globe valves to ensure perfect fitment.
• Maintains accurate valve stem alignment, reducing premature wear on packing and seals.
• Supports high-temperature fluid handling across standard HVAC heating and cooling cycles.
• Simplifies commercial valve repair by serving as a direct replacement for worn or damaged original bonnets.
• Constructed for resistance against the rigorous pressure-temperature fluctuations of closed-loop systems.

Common Questions:

Can this bonnet be used for 3-way mixing valves?
No, this specific assembly is tailored for the 2-way V5011A series. For mixing or diverting applications, the V5013 series components should be utilized.

Does this assembly include the stem packing?
This is the primarily the bonnet housing; however, for a complete rebuild, it is recommended to pair this with a compatible stem packing kit for a leak-free seal.

Is this compatible with pneumatic actuators?
Yes, it is designed to provide the necessary mounting base for standard pneumatic diaphragm actuators and electric linkages commonly used on 3-inch V5011A valve bodies.
