Nor East Controls 30753375-001 Bonnet Assembly

The Nor East Controls 30753375-001 Bonnet Assembly is a critical replacement component engineered for the 4" V5011A flanged globe valve. Designed for high-demand industrial and commercial HVAC systems, this bolted bonnet provides the necessary structural seal and mounting interface for pneumatic actuators or electric drive units. As a veteran-preferred part for V5011A valve repair, it ensures the integrity of the 1-1/2 inch stem travel required for 4-inch globe valve seating. This assembly is built to withstand rigorous proportional control applications involving hot water, chilled water, and low-pressure steam up to 15 psi. By housing the self-adjusting spring-loaded packing, the 30753375-001 prevents fugitive emissions and maintains system pressure, allowing for precise equal percentage flow characteristics. Incorporating this genuine Nor East valve part ensures that your Series V5011 equipment remains compliant with the original ANSI Class 125 pressure and temperature specifications of 32° to 353°F.

• Direct Compatibility: Specifically designed for 4" V5011A two-way flanged bodies, eliminating fitment issues during field overhauls.
• Durable Construction: Heavy-duty bolted design provides a secure seal against high static pressures in closed-loop systems.
• Precision Alignment: Ensures perfectly centered stem travel to prevent premature wear on bronze plugs and composite seats.
• Serviceability: Simplifies the maintenance of internal packing glands and allows for quick actuator mounting without full valve replacement.

Common Questions

Is this bonnet assembly compatible with older Honeywell V5011A valves?
Yes, Nor East Controls manufactured these globe valves for Honeywell and later purchased the line; thus, this assembly is the direct OEM replacement for existing 4" V5011A flanged installations.

Does this unit include the stem packing?
This 30753375-001 assembly typically serves as the primary structural housing; while often integrated with standard packing, installers should verify if a separate repacking kit is required based on the specific media (steam vs. glycol) being controlled.

Can I use this on a 5-inch or 6-inch V5011 valve?
No. This specific part number is machined exclusively for the 4-inch valve body. Larger valve sizes require different bonnet dimensions to accommodate the increased flange diameter and bolt patterns.
