Marine Globe Valve

Marine Globe valves are some of the most versatile valves in marine applications. They derive their name from their round, globular body. There are 3 Types of Marine Globe Valve.

Marine Globe valves are some of the most versatile valves in marine applications. They derive their name from their round, globular body. Globe valves are great at modulating, or “throttling”, flow because of their internal makeup. In a globe valve, water or another medium travels in the bottom inlet of the valve passes up past the seat, and out of the outlet. To stop the flow, a disc is lowered onto the seat in the middle of that S shape. However, this s-shaped configuration creates a large amount of resistance within the valve.

The design of the marine globe valve body forces the flow of the commodity to change direction within the valve itself. This change in direction creates substantial pressure drop and turbulence. The globe valve is therefore not recommended when flow resistance and pressure drop are to be avoided. In most installations, the commodity is routed into the valve’s body from below the valve seat and disc. This flow direction uses the pressure of the commodity to aid in the opening operation of the valve. It also reduces wear on the valve seats and disc.
