BAILEY安全阀746系列产品介绍及选型

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.
