Nor East Controls 30736389-503 Gasket Kit

Maintaining pressure integrity in your critical systems requires high-grade sealing components. The Nor East Controls 30736389-503 Gasket Kit is a comprehensive low-temperature gasket set specifically engineered for 1-1/2" Series 9100 Cage Valves. This kit includes the three essential primary sealsùthe bonnet gasket, top cage gasket, and bottom cage gasketùdesigned to operate efficiently in environments reaching up to +450?F (+232?C). As a professional-grade control valve repair kit, it ensures a leak-proof interface between the valve body and internal cage assembly, preventing bypass and maintaining tight shutoff during high-cycle industrial processes.

For veteran technicians, the 30736389-503 serves as a critical OEM replacement gasket for Nor'East (formerly Honeywell/DeZurik) globe valves. Using industrial-grade valve seals from this kit during routine maintenance or full overhauls prevents the risk of bonnet blow-offs and system depressurization. These mechanical system gaskets are compatible with diverse media, including refined oils, glycols, and natural gas, provided the temperature remains within the specified low-to-medium thermal range. Precision fitment ensures that 1.5-inch cage-guided valves retain their original flow characteristics and failsafe positioning accuracy without requiring field modifications.

• Precise 1-1/2 Inch Fitment: Tailored specifically for Series 9100 cage valves to eliminate sizing errors during field service.
• Complete Three-Piece Set: Includes necessary seals for the bonnet and both top/bottom cage interfaces in one package.
• High Temperature Resilience: Rated for low-temperature applications up to +450?F, suitable for HVAC and light chemical processing.
• Reliable Leak Prevention: Designed to maintain internal seal integrity, preventing fluid bypass and pressurized leaks.
• OEM Compatibility: Replaces legacy Honeywell and DeZurik parts seamlessly within existing Nor'East globe valve installations.

Is this kit compatible with high-pressure steam services?
This specific kit is rated for low-temperature applications up to 450?F. For high-pressure steam exceeding this thermal threshold, you should reference the high-temperature equivalent (part 30736389-504) to ensure elastomer stability.

Does this kit include the valve packing or O-rings?
No, the 30736389-503 focuses on the primary cage and bonnet gaskets. Seat ring O-rings and stem packing are typically sold separately or as part of a more extensive trim repair kit.

Should I replace these gaskets every time I disassemble the valve?
Yes. To avoid potential leakage after reassembly, technical standards dictate that the bonnet and cage gaskets should be replaced whenever the valve is opened for inspection or overhaul.
