The marine deck surface valve is a critical component used on ship decks for controlling the flow of fresh water, seawater, and sewage. It is designed for durability and secure sealing in demanding marine environments.
Structure
The valve is built with a connecting bottom plate, a support, and a valve rod. The bottom plate and support are joined by nuts and stud bolts, which pass through the plate cavity to ensure firm assembly. Both ends of the support are reinforced with a U-shaped bracket for stability.
Working Principle
The valve rod passes through the U-shaped support and links to the valve disc with a compression nut. A control pad at the contact surface helps reduce friction and wear. Inside the cavity, the disc presses against an O-ring, forming a tight seal. The up-and-down motion of the stem drives the disc, and when fully engaged, the entire valve is sealed effectively.
Application
This surface valve is suitable for ship deck systems operating within a medium temperature range of 10 °C to 80 °C. It performs reliably in systems carrying fresh water, seawater, and sewage, making it an essential valve for marine service.
