Kunkle Valve Bailey 746 Safety Relief Valve

The Kunkle Valve Bailey 746 Safety Relief Valve, engineered by Emerson, is a high-performance safety device designed to provide reliable overpressure protection in steam, air, gas, and liquid systems. Built for industrial, marine, and power generation applications, the Bailey 746 ensures accurate pressure relief, tight sealing, and durable service under the most demanding operating conditions. Manufactured to meet ASME Section I and VIII standards, the Kunkle Bailey 746 valve offers precision-engineered components for consistent operation and rapid reseating. Its semi-nozzle, full-lift design delivers maximum discharge capacity while maintaining stable performance across a broad range of pressures and media. The valve’s robust construction, stainless steel trim, and corrosion-resistant materials make it suitable for both clean and corrosive process applications. With a variety of end connections, set pressure ranges, and orifice sizes, the Bailey 746 can be configured to meet the specific needs of critical protection systems in boilers, pressure vessels, pipelines, and process plants.

Feature of Kunkle Valve Bailey 746 Safety Relief Valve

• Freely pivoting disc ensures correct alignment with the nozzle.
• Highest possible discharge rate maximizes plant protection.
• Special disc style for liquid applications enhances valve performance.
• Conventional arrangement suitable for applications where built up pressure will not exceed 5%.
• Conventional valve can also be used in systems with constant superimposed backpressure (up to 80%).
• Balanced bellows arrangement for applications where several safety relief valves discharge into a common discharge manifold or for variable back pressures to 40%.
• Choice of cap options.
