Bailey 480 Cartridge Assembly Relief Valve

**Product Description** Globe valves are linear motion shut-off valves designed specifically to control or halt the flow of fluids. They consist of a body, bonnet, internal plug, stem, and seat ring. The distinctive design of globe valves provides excellent sealing capabilities, even under low-pressure differentials, making them ideal for applications that necessitate precise throttling. These valves are predominantly employed in isolation, flow control, and pressure-regulated applications. **Features** Globe valves are highly versatile, featuring an angle-seated design that ensures effective shut-off capabilities while enduring wear and tear. Unlike gate valves, globe valves allow for precise flow regulation. They are available in either union or bolted bonnet configurations. The disc of the globe valve moves in parallel with the flow and employs a stem and disc assembly to manage fluid flow. By turning the handwheel, the valve stem rises, adjusting the position of the disc, which either restricts or permits flow according to its setting. **Materials** - **Body/Bonnet:** NAB (ASTM B148 C95800) - **Seat:** NAB (ASTM B148 C95800 / ASTM B150 C63200), MONEL (ASTM A494 GR.
