Self Closing Valve
A marine self-closing valve is an essential component designed to automatically revert to a closed position after manual operation. These valves are extensively utilised on ships to prevent unintentional fluid discharge, enhance safety, and ensure adherence to pollution and fire prevention regulations.
What is a Marine Self-Closing Valve?
This type of valve features a spring-loaded mechanism that opens upon manual activation, typically via a lever or push button, and automatically closes once the operator releases it. In its default state, the valve remains closed, thereby preventing the unintended discharge of fluids such as fuel, oil, or bilge water.
We offer a comprehensive range of Self-Closing Valves from leading manufacturers. For further information or to discuss your specific requirements, please do not hesitate to get in touch with us.
