What Is The Difference Between Marine Globe Valve And Marine Globe Check Valve
While both marine globe valves and marine globe check valves feature a similar design with a movable disk and a stationary seat, the key difference lies in their functionality. Globe valves are primarily used for flow regulation, while globe check valves are designed to allow flow in one direction only and prevent backflow, making them essential for ensuring the integrity and safety of marine systems.
Overview
Marine Globe Valve:
A marine globe valve is a type of valve used to regulate flow in a pipeline. It consists of a movable disk (or plug) and a stationary ring seat. When the valve is open, the disk is lifted away from the seat, allowing fluid to flow through the valve. When the valve is closed, the disk is pressed against the seat, stopping the flow of fluid. Globe valves are commonly used for throttling or regulating flow.
Marine Globe Check Valve:
A marine globe check valve combines the functions of a globe valve and a check valve. It allows fluid to flow in only one direction, preventing backflow. Like a globe valve, it has a movable disk and a stationary seat. However, unlike a standard globe valve, a globe check valve also has a mechanism to prevent reverse flow. This mechanism typically consists of a spring-loaded disk or a swing check mechanism.
