Nor East Controls 30046366-859 Gasket

The Nor East Controls 30046366-859 Gasket is a critical replacement component engineered for high-performance sealing in 4-inch pneumatic control valves. Designed specifically for industrial HVACR applications, this non-asbestos sheet gasket (Suffix -859) is built to handle high-temperature environments ranging from -29? to +399?C (-20? to +750?F). Whether you are servicing Series V5011 globe valves or Series 9100/9200 cage valves, this replacement valve gasket ensures a high-integrity seal between the bonnet and body, preventing fluid or gas bypass that leads to system inefficiency. Its precise fit is essential for maintaining the 1.5-inch travel stroke calibration on 4-inch units, providing the HVAC valve sealing properties required for steam, hot water, and chilled water loops. As a genuine Nor East Controls spare part, it meets strict industrial standards for 4 inch valve maintenance, ensuring long-term seat integrity and pressure containment without the need for frequent re-torquing.

• High-Temperature Resilience: Engineered as a non-asbestos gasket capable of withstanding extreme thermal cycles up to 750?F.
• Exact Compatibility: Specifically designed for 4-inch Nor East Controls V5011 and cage-style valves to eliminate leakage.
• Industrial Durability: Robust material construction resists wear from steam, glycol, and various chemical treatments.
• System Efficiency: Maintains precise bonnet alignment to ensure consistent valve modulation and shut-off.

• Is this gasket compatible with older Honeywell or DeZurik valve bodies? Yes, since Nor East Controls continues the manufacturing legacy of these lines, this part is the correct technical replacement for many legacy 4-inch globe valve configurations.
• What temperature range can this gasket handle? This -859 suffix part is rated for high-temperature service from -20?F up to 750?F.
• Where is this gasket used in the valve assembly? It is typically utilized as the primary seal between the valve bonnet and the valve body or cage assembly.
