ABOUT US

Marine Valve Manufacturer

Marine industry requires reliable and high-quality equipment. This is to provide long-lasting service especially when this industry is exposed to corrosive seawater.

A surface ship has an average of 4000 valves. These valves types include globe valve, check valve, SDNR valve, hose valve, gate valve, storm valve, butterfly valve, quick-closing valve, air vent head and etc.

They are important for the marine industry to control the gas and liquid flow on board ships, boats, and other marine vessels.

Different Valves Used in Marine Industry

Ball Valves

We manufacture marine ball valves that are commonly used in piping systems on board ships, as they are easy to operate and maintain.

Gate Valves

Our marine gate valves are commonly used in different marine applications that require a full flow of fluid or where a low-pressure drop is required.

Butterfly Valves

Grand Ocean marine butterfly valves have a disc that rotates around a central axis to control the flow of fluid. These valves are easy and quick to install.

Globe Valves

We manufacture marine glove valves that features a disc that moves up and down. You can use it for applications that require precise control of the flow rate.

Check Valves

Our marine check valves are used are used to control the flow of fluid in one direction, preventing backflow. Thus, damage and contamination are prevented.

Sea Suction Valve

We manufacture sea suction valves that are used for controlling the flow of water in a ship’s exterior. These are operated using a hand wheel.

IMPORTANT

Important Aspects of Marine Valves

Materials

Marine valves are typically made from materials that are resistant to corrosion and erosion, such as bronze, brass, stainless steel, and cast iron. The choice of material depends on the type of fluid or gas being transported, the pressure and temperature of the fluid, and the specific environmental conditions.

Applications

Marine valves are used in various applications onboard a ship, including the main engine, auxiliary machinery, seawater cooling system, fuel system, air conditioning system, and ballast system. They are also used in offshore platforms, FPSOs, and other marine structures.

Standards

Marine valves are subject to various standards, such as the American Petroleum Institute (API) standards, and the GB, JIS or DIN standards. These standards ensure the quality and safety of marine valves and their compliance with industry standards and regulations.

Maintenance

Proper maintenance and regular inspection of marine valves are essential to ensure their proper functioning and to prevent accidents and downtime. Maintenance procedures typically include cleaning, lubrication, testing, and replacement of worn-out components.

FAQs

When selecting valves for the marine industry, it is important to consider factors such as the type of fluid being transported, the pressure and temperature of the fluid, and the size and location of the valve.
Generally, the working principle of a marine valve involves controlling the flow of fluid by opening or closing a passageway using a disc or other element that moves or rotates inside the valve body.
