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.

JIS F7388 specifies a type of bronze globe valve used in shipbuilding and related industries, often with a 20K (20 kgf/cm²) pressure rating. It's commonly used in marine applications and features connections like U (union) or S (screw) ends. The valves are manufactured to comply with JIS F7400 standards and are available in various sizes and materials, including bronze and brass. 
Here's a more detailed breakdown:
Type: Globe valve, often with a rising stem and a union or screw connection. 
Pressure Rating: Typically 20K (20 kgf/cm²), which is equivalent to 20 Bar or approximately 290 psi. 
Materials: Commonly uses bronze for the body, stem, and disc, but other materials like cast iron, ductile iron, cast steel, forged brass, stainless steel, and forged steel can be used. 
Standards: Manufactured according to JIS F7400 standards. 
Applications: Primarily used in shipbuilding, ship repair, and oil platforms. 
Connections: Available with U (union) or S (screw) connections, corresponding to JIS B2220 flange dimensions for steel pipes. 

Bronze 20K Globe Valve for Marine Use JIS F7388 is a kind of ferrule type valve, used to connect the small size pipe, and shut off and turn on the medium in the pipeline. There are S type and U type. S type is screw end, U type is union type.
Technical Specification:
1. Design and Manufacturing Standard: JIS F7388
2. Suitable Medium: Steam, Fresh Water, Fuel Oil and Lubrication Oil
3. Hydraulic Test Pressure: Body-4.20Mpa, Seat-3.08Mpa
4. Max Working Pressure: 1.6Mpa for Steam of 205ºCor less, 2.0Mpa for air, gas, oil and plusation water, 2.8Mpa for non-shock water of 120ºC or less.
Main Material:
1-Body: Bronze (BC6)
2-Disc: Brass
3-Stem: Brass (C3771BD)
