Flow control valves: characteristics and applications in the naval industry.
Flow control valves are used to limit and regulate the flow of liquids, gases or a mixture of both. In this article, we will delve into the function of the flow control valve and its applications in the naval industry.
What are flow control valves in the naval industry?
Flow control valves regulate the flow of liquids and gases in a system. Valves may be open or closed to allow or stop flow. In a wide variety of applications, flow control valves are used highlighting among others the naval industry.Globe valves, gate valves, ball valves, check valves and diaphragm valves are some of the different types of flow control valves. It is important to choose the right flow control valve for the application.
How do flow control valves work?
The main functions of the valves are to direct the flow of fluids, regulate the pressure and control the flow of fluids. Flow control valves work by regulating the opening and closing of an opening to allow or stop the flow of a fluid.
Flow control valves can open or close manually or automatically. Manual valves are opened or closed by a crank or lever, while automatic valves are opened or closed by a system controlled by an electronic or mechanical device, such as a solenoid valve or controller.
Directional control valve, pressure control valves and flow control valve are some of the different types of valves whose function is to regulate pressure and control fluid flow. In some cases, these flows need to be controlled to reduce the input of fluids to certain components. Then, in such cases, hydraulic flow control valves are used. Regulating the speed of the cutting tool, spindle, flat grinder, etc. are some of the applications of these valves. In addition, most agricultural constructions and heavy machinery use these hydraulic valves. Simple structure, simple operation and a wide range of adjustments are the advantages of flow control valves.
The main purpose of the flow control valve is to regulate the flow of fluids to various components in a hydraulic circuit. Other functions are to regulate the speed of linear and rotary actuators, regulate the availability of energy for the subcircuits, divide and regulate the flow of the pump, etc.
In general, flow control valves are a key component in many industrial and commercial systems, as they allow to regulate and control the flow of liquids and gases accurately and safely.
Characteristics of flow control valves.

Types of flow control valves.
There are different types of flow control valves available on the market. Gate valve, globe valve, sleeve valves, diaphragm valves and check valves are some of the main categories.
- Gate Valve: Gate valves are compatible with a wide range of fluids and are suitable for high pressure and high temperature applications. These valves are used for strangulation-free opening/closing services that require a straight-line fluid flow with a minimum restriction of gate valves. However, these valves are not suitable for sludge and viscous fluids. Vibration and slow response characteristics are the drawbacks of gate valves.
- Globe valve: Globe valves are linear motion valves to stop, start and regulate flow. These valves are used for opening/closing and regulating applications. The globe valve is a general purpose flow control valve that is used for high temperature applications. These valves are comparatively faster and more reliable with limited wear to the seat disc under partial opening conditions.
- Sleeve valve: Sleeve valves are low cost flow control valves suitable for slurries or liquids containing significant amounts of suspended solids. These valves provide 100% airtight closures and are used in the food, chemical, wastewater and beverage industries.
- Diaphragm valve: Diaphragm valves are an important category of flow control valves used for throttling services. These valves are suitable for applications using corrosive liquids at low temperature and pressure. Diaphragm valves have leak-proof seals that ensure tight seals. In addition, these valves are extremely clean and easy to maintain.
- Check valve: Check valves are unidirectional valves used in pumps, aircraft hydraulics, sprinklers, etc. These valves contain two ports, for entering and unloading fluids. By preventing fluid reflux, these valves will protect the pumps and compressors in the system. Maintaining pressure and serving as a backup system are the important advantages of check valves.
