There is a wide range of valves used on ships such as check valves, butterfly valves, etc, and each one of them has unique applications. This is why the marine industry has a high demand for expert check valve suppliers and other types of valve supplies as well.

Commonly, the valves are used to regulate the fluid flow and pressure of the engine systems, pipeline, and other mechanical components onboard, therefore, managing the ship’s optimal functioning. The valves installed and used on ships are also able to carry vapors, gasses, and mixed fluids so they find innumerable applications.

In this guide, you will learn about different types of valves installed and used onboard ships. Keep reading till the end to find out more.

Check Valves

The main purpose of a check valve is to ensure that there is no backflow. These valves enable the flow of a medium to occur only in one direction and work on the pressure difference. The overall build of a check valve is pretty simple having a small cylinder with two ports acting as the inlet and outlet.

Check valves are commonly referred to as “non-return valves”. The mechanism of this type of valve is based on its various types. A standard check valve allows the medium flow when the inlet side has a higher pressure. 
The highlighting feature of these valves is that they don’t have the requirement for a handling mechanism, be it mechanical or automated. These valves are handy installations in any situation where there’s a concern of backflow causing an issue.

In the marine industry, the use of check valves is carried out in several circumstances including fuel handling, desalination, and hydraulics. Check valves are known to be one of the most common types of valves used onboard ships as the valves can be employed in complex and crucial environments as per the requirement.

Globe Valve

If any system onboard a ship requires the controlled flow of any media, the globe valves are the perfect solution. Globe valves are linear motion valves that can start/stop, and have efficient control of the flow medium. 

The valves are spherical in construction having two parts of the body of a globe valve divided with an internal baffle. They are also known as throttle valves. This type of valve uses the perpendicular motion of the disk to regulate the media motion in a pipeline. 

Unlike the other valves such as ball valves and butterfly valves, the globe valves are the right choice for the regulation of fluids. The functionality and structure of a globe valve allow the media control to be established in both directions within the pipeline. 

This valve is commonly found in water faucets. Besides manual handling, these valves are also controlled using pneumatic or electric actuators, particularly in large-scale applications.

Butterfly Valves

Butterfly valves have a simple build and primarily deliver the function of used shut-off. Due to their lack of proper sealing, they are not generally used for controlling the flow of any medium. 

This industrial-type valve has a disk connected to a rod and this setup gives the name “butterfly” to this valve. They are quarter-turn rotational valves and 90° rotation of the disk enables the valve to close or open. 

Manual or automated motor handling of the valve is available for its operation. The overall design of a butterfly valve is in such a way that it eliminates the contact between the body of the pipeline and the flowing media.

There are other types of valves used for onboard ships. Whether you’re searching for any specific type of valve supplier like the check valve suppliers or a distributor offering a variety of valves, be sure to get in touch with expert valve suppliers to get a range of valve options for the marine industry.
