Nor East Controls 30731056-001 Stem

The Nor East Controls 30731056-001 Stem is a precision-engineered replacement component specifically designed for the Honeywell V5011B globe valve series with 5" body sizes. As a veteran-grade part, this stem ensures the structural integrity and linear travel required for accurate proportional control of steam and water in high-demand industrial and commercial HVAC systems. Manufactured to the original rigorous standards, it facilitates a 1-1/2 inch stem travel (stroke), allowing the 30731056-001 to maintain the tight shut-off and modulation performance your hydronic or steam loop demands.

Constructed from high-grade stainless steel, this valve stem assembly is built to withstand the repetitive cycling and thermal stresses encountered in heavy-duty globe valve applications. By replacing a worn or pitted stem with this OEM-spec part, contractors can restore original flow characteristics and prevent packing leaks or actuator hunting. This stem is compatible with both pneumatic and electric actuators, ensuring seamless integration into existing building automation frameworks without requiring extensive recalibration of the linkage or drive assembly.

• Precision Compatibility: Exact fit for 5-inch V5011B valves, eliminating the risk of seat misalignment or stroke errors during field repairs.
• Material Durability: Stainless steel construction provides superior resistance to corrosion and wire-drawing in steam and water applications.
• Optimized Modulation: Supports stable stem travel to ensure consistent flow coefficients and prevent system oscillations.
• Mechanical Reliability: Restores smooth movement through the packing gland, reducing wear on actuator linkages and internal seals.

Is this stem specific to the 5" valve body?
Yes, the 30731056-001 is sized specifically for the 5-inch Honeywell V5011B series to accommodate the 1-1/2" stroke requirement.

Can I use this for both steam and chilled water systems?
Correct. This stainless steel stem is rated for the pressures and temperatures typical of both steam heating and chilled water cooling loops.

Do I need to replace the seat or packing when installing this stem?
While not always required, we recommend inspecting the packing gland and seat whenever the valve trim is disassembled to ensure a proper seal and long-term performance.
