Valves play a very critical role in the marine industry. As ships become larger and are used more frequently, they require the ability to generate power, treat and manage wastewater and control HVAC, as well as perform their required tasks. The size and application of the ship will determine the different types and number of valves on board. Valves are used for almost all machinery systems on ships. Valves are used to regulate the loading and storage of a ship’s power supply, provide water for fire-fighting capabilities, handle and processes wastewater and store any liquid cargo, among many other applications. Any valve that processes sea water must be durable, and all marine valves must be reliable due to lack of resources once out at sea.
The most common valves on ships and barges are the gate, globe, check, Ball & Butterfly valves. Extra space is always at a premium on a ship.
Other types of maritime valves & related items used are Strainers, Quick Closing Valves, Storm Valves, Fire Hose Valves, Safety Valves, Expansion Joints, Couplings, Level Gauges, etc.
Gate Valve is among the most commonly used valves onboard ships. It is also one of the simplest valves in terms of design and functionality. As the name suggests, a gate valve consists of a simple mechanism called “the gate” or the valve disc, which performs the main function of regulating the flow of the fluid.
The next most common type of valve to be used onboard ships in places such as bilge suction lines is Globe valve. It is a linear motion valve, which regulated the flow of the fluid, the valve has a globe-shaped body that houses the valve seat and the disc. The general arrangement of a globe valve consists of the valve seat and the disc arranged at a right angle to the axis of the valve. The perpendicular movement of the disc, away from the valve seat, causes a space between the disc and the disc ring, which opens the valve.
The next in line is check valves. High-performance non-return check valve custom designed specifically for use in wakeboard ballast system applications. These valves are used for preventing siphon draining, drain above the waterline, and share one thru-hull connector.
Along with these valves, we also offer high quality, high-pressure resilient-seated butterfly valves to meet the requirements of today's industrial/marine markets. This valve is specifically designed for onshore and offshore fire protection.
