Globe valves start, stop, and throttle the flow of compatible media within a system. These valves have a disc at the end of their stem which is lowered or raised into or from the seat to stop and regulate flow. As the disc is lowered closer to the seat, flow rates decrease. Raising the disc away from the seat increases flow rates. Globe valves provide a tighter seal and precision control over flow regulation than other throttling valves. General-service manual globe valves use a hand-operated lever to control media flow in various industrial and commercial applications. Pneumatically-actuated globe valves use compressed air to control media flow and have a higher closing force than electrically-actuated valves, suitable for systems moving viscous liquids. Electrically-actuated globe valves open and close faster than pneumatic valves without creating pressure surges. Boiler blow-down manual globe valves use a hand-operated lever to drain impurities from boiler tanks.
