BAILEY安全閥746系列產(chǎn)品介紹及選型
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.
GENERAL APPLICATION
The 746 is certified to BS6759 pt 1, 2, 3 and is suitable for the protection of vessels, pipelines and equipment using hot or cold water; air; process or corrosive liquids and for clean steam and gases in hygienic environments.
