Product Description
What is gate valve?
A marine gate valve is a specialized type of gate valve designed for use in shipboard and offshore applications to control the flow of liquids (e.g., seawater, fuel, or ballast water) in pipelines.
Key Characteristics:
Durable Construction - Made of corrosion-resistant materials (e.g., bronze, stainless steel) to withstand harsh marine environments.
Bidirectional Flow - Suitable for systems requiring flow control in both directions.
Tight Seal - Ensures minimal leakage when closed, critical for safety and efficiency.
Slow Operation - Prevents water hammer, protecting pipeline systems.
Common Uses in Marine Systems:
Ballast water management
Engine cooling systems
Fuel transfer pipelines
Types Mentioned in Marine Contexts:
Sliding Gate Valve: Used in ship locks or watertight compartments
Lock Valve: A sub type for ship lock water discharge control.
For specific valve standards or installation examples, further technical documents may be required.
