Kunkle Bailey 746 Safety relief valve
A top guided, full lift safety relief valve with an unobstructed seat bore to ensure the highest possible discharge rates, with the choice of conventional or balanced bellows designs
Features
- 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.
