NABIC 500L Pressure Relief Valve

A marine mud box is a specialised coarse strainer installed in the suction line of seawater systems on board vessels, typically situated before the seawater pump. Its primary function is to filter out large debris such as seaweed, sand, mud, and marine organisms from the seawater intake, thereby safeguarding downstream equipment, including pumps, heat exchangers, and piping systems.

Key Benefits of a Marine Mud Box

• Protects seawater pumps and piping systems from blockages and potential damage.
• Prevents fouling within cooling, ballast, firefighting, and general service systems.
• Captures large solids that could otherwise pass through the sea chest grating.

We offer a range of marine mud boxes from several leading manufacturers. For specific requirements or inquiries, please do not hesitate to contact us.

The Reliance Water Controls (RWC) TPR28 Pressure and Temperature Relief Valve is designed to safely discharge water, effectively preventing damage to hot water cylinders caused by excess pressure or high temperatures. These high-capacity valves are essential for both domestic and commercial applications, ensuring protection against over-pressurisation and temperatures exceeding 95°C. Such conditions can arise in unvented hot water systems if input temperature or pressure controls fail. The TPR28 Valve is specifically designed for installation at the upper section of a hot water cylinder, where the water reaches its highest temperatures. When activated, the valve lifts off its seat, allowing water to be released safely, thereby reducing both pressure and temperature within the cylinder.
