Naval Applications: Types of Valves Used on Ships
To keep the power of an entire Navy fleet operational, you need to ensure you use the right
What kind of equipment does the Navy trust to keep their ships in top shape?
Here we will look at the types of valves the Navy uses and their designs.
Different Types of Valves
Valves are one of the most important pieces when dealing with any fluid. This makes them key on
a large naval ship.
A valve controls the distribution and pressure of various fluids. A large variety of machinery in
ships run with the regulating flow of liquid.
Valves come in a large variety. Their size is often dictated by the size of the system.
The designs of each type of valve center around how their mechanism works. Some popular valve
designs are the shutoff, the ball, the needle, the butterfly, and the pinch.
One popular valve used in the Navy is the gate valve.
The Gate Valve
The gate valve is a simple and effective design. It takes its name after its base mechanism.
A gate valve has a simple mechanism. As the valve turns, a device raises or lowers to control the
flow of liquid.
This simplicity is why it is a well-used design. Over-complication when creating any sort of
mechanical structure will only lead to trouble.
A Variety of Designs
Though a gate valve may be simple, it can still have variations in its design. The major design
differences sort into two types; there is the rising stem and the non-rising stem.
A rising stem design has threads on the on the stem that connects it to the yoke of the valve.
A non-rising stem has the opposite effect. It instead has threads that connect the gate to the stem.
What does this all mean? The rising stem design does as it says: the stem rises when used. Because
of this, many prefer the non-rising stem in tight environments.
The Pros and Cons of the Gate Valve
In either design, gate valves work against the flow of water. The gates will stop the flow of liquid,
which can cause stress on the rest of the system.
Keeping a close eye on the system can prevent any sort of problems from occurring. Either way, it
is still a downside to the design.
The main use of a gate valve is to allow the fluid to flow in both directions with ease. As well, due
to its downside, the gate valve has to create a low-pressure system.
Regular maintenance is key. The gland packing used to stop water leakage will need to be replaced
at regular intervals.
With simplicity and solid strength, the gate valve is a trusted structure of Navy ships.
