Nor East Controls 30731054-001 Stem

The Nor East Controls 30731054-001 Stem is a precision-engineered replacement component specifically designed for 4" V5011 Globe Valves. Built to withstand the rigorous demands of industrial HVACR applications, this stainless steel valve stem ensures the 1-1/2 inch travel required for accurate modulating control of steam, water, and glycol-based systems. As a critical part of the V5011 valve assembly, it maintains a tight seal when paired with spring-loaded PTFE packing, preventing hazardous leakage in high-capacity 4-inch flanged valve bodies.

For veteran contractors performing commercial HVAC maintenance, this stem assembly is the standard for restoring linear or equal percentage flow characteristics. Replacing a bent or scored Honeywell V5011 stem is essential for preventing actuator binding and ensuring the globe valve performance remains within specification for building automation systems. Designed for field serviceability, this part facilitates the repair of single-seated valves without requiring a full body replacement, maximizing system uptime and operational efficiency in large-scale hydronic loops.

• Precision Compatibility: Engineered as the exact replacement valve stem for specifically the 4-inch V5011 series, ensuring perfect fitment with existing 05 and Modutrol IV actuator linkages.
• Enhanced Durability: High-grade stainless steel construction resists corrosion and scoring, common issues in systems with steam cavitation or high mineral content.
• Optimized Flow Control: Supports the full 1.5" stroke length necessary to achieve a 160 Cv rating, maintaining the throttling plug accuracy required for precise temperature regulation.
• Leakage Prevention: Smooth surface finish minimizes friction against the spring-loaded packing, extending the service life of the valve seal.

• Is this stem compatible with smaller V5011 valves? No, the 30731054-001 is sized specifically for 4" flanged bodies; smaller 1/2" to 3" valves typically utilize a 3/4" stroke stem and are not cross-compatible.
• Can this be used in both direct and reverse acting configurations? Yes, this stem is designed to function within the 4-inch V5011 valve architecture regardless of the actuator action, provided the internal plug assembly is correctly seated.
• What are the symptoms of a failing valve stem? Indicators include external leaking at the packing nut that persists after tightening or visible binding where the actuator fails to move the valve through its full 1.5-inch travel range.
