Nor East Controls 30041050-835 Composite Disc

The Nor East Controls 30041050-835 Composite Disc is a critical trim component engineered specifically for the Honeywell V5011 series of single-seated globe valves. Designed for industrial-grade performance in HVAC water and steam systems, this disc is the primary sealing element required to maintain tight shut-off and precise throttling. As a veteran-preferred V5011 replacement part, it is constructed from high-durability composite materials capable of withstanding the thermal stressors common in low-pressure steam (up to 20 psi) and chilled or hot water loops.

When performing field service on pneumatic globe valves or electric-actuated V5011 units, installing a 30041050-835 seat disc ensures the valve retains its original equal percentage flow characteristic for water or linear scaling for steam. This composite seat is chemically resistant and designed to prevent seat leakage and "hunting" in modulating control applications. Proper fitment within the disc holder is essential for maintaining the 3/4-inch or 1-1/2-inch travel specs required for accurate temperature regulation in commercial facilities.

• System Compatibility: Drop-in replacement for Nor East and Honeywell V5011 valves ranging from 2-1/2 to 6 inches.
• High-Temperature Resilience: Engineered for low-pressure steam and hydronic applications, supporting consistent sealing in diverse ambient conditions.
• Precision Sealing: The composite material provides a superior seal compared to metal-to-metal seats, reducing bypass and energy loss.
• Contractor Grade: Simplifies valve rebuilding and HVAC repair by meeting exact OEM dimensional tolerances.

Common Questions:

Which valve models use the 30041050-835 disc?
This disc is specifically designed for the V5011 series (including V5011A and V5011B) medium-duty globe valves. It is often found in systems utilizing Type 05 pneumatic actuators or Modutrol motors.

Is this part suitable for high-pressure steam?
The composite disc is optimized for low-pressure steam applications up to 20 psi. For high-pressure steam service exceeding these specs, a stainless steel or specialized metal-seated plug may be required depending on the valve body class.

Can I replace just the disc or do I need a full trim kit?
While the 30041050-835 can be replaced individually to address seat leakage, technicians often inspect the stem packing and gaskets simultaneously to ensure a complete seal during a rebuild.
