Technical Specification
Overview
Key Features and Engineering:
Immediate Shutdown: The valve is designed for instant closure to cut off the flow of fuel oil or lubricating oil during an emergency, such as an engine room fire or a pipeline rupture.
Safety Enhancements: Its engineering includes a downward flow channel that reduces spring load, improving safety and allowing for a smaller, more cost-effective spring. The design also features an ultra-compact form to save valuable space onboard.
Dual Operation: To ensure functionality in any scenario, the valve can be operated locally via a manual lever or remotely using a pneumatic (air) cylinder-
The pneumatic system allows for rapid closure from a safe, remote location.
