Nor East Controls 30067841-316 Stem Assembly

The Nor East Controls 30067841-316 Stem Assembly is a critical mechanical component engineered for high-precision flow regulation within commercial globe valves. Designed as a direct replacement part, this 16-inch overall stem assembly is specifically utilized in Nor East Series 8600 mixing valves and Series 8900 diverting valves. Constructed from 316 stainless steel, this assembly provides superior resistance to stress-corrosion cracking and chemical degradation, ensuring reliable linear valve travel and precise alignment under varying thermal loads. This heavy-duty stem is essential for maintenance professionals servicing Type 05 pneumatic actuators, offering the structural integrity required to maintain the spring-return failsafe positions in critical HVACR and process control loops. By using OEM-spec 316 SS material, technicians can prevent early stem pitting and packing leaks, maintaining the mixing valve performance necessary for accurate fluid temperate control in boilers and chillers.

Key Benefits

• 316 Stainless Steel Construction: Engineered for maximum corrosion resistance in aggressive hydronic and steam environments.
• Precision Machined 16" Length: Maintains exact actuator-to-plug alignment to prevent binding and ensure consistent flow coefficients (Cv).
• High Compatibility: Direct replacement for Nor East Controls V5013 series and related 2-1/2" to 3" globe valve bodies.
• Industrial Durability: Built to withstand the high cycle rates of pneumatic diaphragm actuators without losing dimensional stability.

Common Questions

What valves are compatible with the 30067841-316 stem?
This stem is optimized for Nor East Controls Series 8600 mixing and Series 8900 diverting cage-style globe valves, typically paired with Type 05 pneumatic actuators.

Why is 316 stainless steel used for this stem assembly?
The 316 SS material is selected for its superior molybdenum content, which protects the valve stem from pitting and crevice corrosion in treated boiler water or cooling tower applications.

Does this assembly include the valve plug or packing nut?
This part number refers specifically to the 16-inch stem assembly; associated components like V-ring packing or the valve plug are typically sourced separately to match specific trim requirements.
