Nor East Controls 30041052-835 Disc

Maintaining positive shut-off in high-volume fluid systems requires precision-engineered internal components like the Nor East Controls 30041052-835. This replacement 5 inch flanged valve disc is specifically designed for integration with Series 8100 single seated cage valves and the V5011 flanged globe valve series. Engineered to handle the rigors of medium duty HVACR applications, this disc facilitates reliable throttling and on-off control for low-pressure steam, chilled water, and hot water systems. Contractors often utilize this part when overhauling ANSI Class 125 cast iron valve bodies where corrosion or scale buildup has compromised the original seating surface.

The 30041052-835 ensures a tighter Class IV shutoff, reducing the risk of bypass leakage that can lead to energy waste and system instability. When performing a valve trim repair, utilizing this OEM-spec disc guarantees technical compatibility with existing 1.5-inch valve travel requirements common in 5" flanged configurations. Its robust construction resists the erosive effects of common water treatment chemicals and thermal cycling, ensuring long-term seat integrity in commercial boiler and chiller loops.

Key Benefits

• Engineered for Series 8100 and V5011 5-inch cast iron flanged valves.
• Optimized for Class IV leakage standards to prevent fluid bypass significantly.
• Supports throttling control in steam applications up to 20 psi and hydronic systems.
• Direct-fit mechanical dimensions eliminate the need for field modifications during valve maintenance.
• Resistant to thermal fatigue and common HVACR chemical additives.

Common Questions

What causes a 5" flanged valve disc to fail?
Failure usually results from wire drawing caused by high-velocity fluid across the seat or wire erosion from debris like welding slag. Regular inspection of the disc and cage during maintenance prevents seat damage.

Is this disc compatible with older Honeywell or DeZurik models?
Yes, since Nor'East Controls acquired these product lines, this part serves as a direct technical replacement for the legacy globe valve series originally manufactured under those brands.

Do I need to replace the gaskets when installing this disc?
Yes, veteran technicians always recommend replacing the bonnet and cage gaskets whenever the pressure vessel is opened to ensure a leak-free seal upon reassembly.
