Product Description

Marine Globe Valve - Definition & Function

A marine globe valve is a linear-motion valve designed for precise flow regulation in shipboard piping systems. Unlike simple on/off valves (e.g., gate valves), it allows fine-tuned throttling of liquids/gases (e.g., seawater, fuel, steam) while maintaining reliable shutoff.

Key Features of Marine Globe Valves

1. Design & Working Principle

• Spherical body with an internal baffle (partition) forcing flow to change direction, increasing resistance for better control.
• Movable disc/plug presses against a stationary seat to regulate flow (screwed via a handwheel or actuator).
• Stem operation: Raises/lowers the disc linearly (unlike rotary ball/gate valves).

2. Why Ships Use Globe Valves

• Accurate flow adjustment: Critical for cooling systems, fuel dosing, or steam lines.
• Positive sealing: Prevents leaks when fully closed (e.g., high-pressure steam isolation).
• Corrosion-resistant materials: Bronze, stainless steel, or duplex alloys for seawater/chemical resistance.

3. Common Marine Applications

• Engine cooling water control
• Fuel oil supply regulation
• Steam system throttling (e.g., boiler feed lines)
• Hydraulic system pressure management

Globe Valve vs. Other Marine Valves

Valve Type	Primary Function	Best for Marine Use When...
Globe Valve	Throttling/flow control	Precise adjustment needed (e.g., cooling systems)
Gate Valve	Full on/off (low resistance)	Main seawater intake (minimal pressure drop)
Ball Valve	Quick on/off operation	Fuel tank isolation (fast shutoff)
Check Valve	Prevent backflow	Bilge pumps, overboard discharges

Pros & Cons in Marine Environments

Pros:

• Excellent for frequent flow adjustments.
• Tight shutoff (less leakage than gate valves).
• Repairable without removing from pipeline.

Cons:

• Higher pressure drop than gate/ball valves (not ideal for high-flow, low-resistance systems).
• Heavier and bulkier than ball valves.
