What is a control valve?

A control valve is a device used in fluid systems to regulate the amount of flow, pressure, or temperature of a liquid or gas through a pipe. It works by adjusting the opening of its internal passage, allowing precise control of the fluid passing through it. These valves can be operated manually or automatically using actuators. They are essential in industrial applications where constant and precise control is required to ensure the efficiency and safety of the system. Types of control valves include globe valves, butterfly valves, ball valves, among others.

What types of control valves are there?

There are different types of flow control valves. Generally, they are used to regulate the flow of a fluid, functioning as an orifice with a variable area that changes the pressure drop according to the signal from a controller. Thanks to them, it is possible to regulate the flow rate and other factors such as pressure, temperature, or level.

They must withstand the temperature and pressure of the fluid without leakage; be appropriately sized for the flow to be controlled; and resist erosion or corrosion caused by the fluid.

Types of hydraulic control valves commonly found in current systems

  • Pressure regulators: they are used to control a downstream pressure from the valve using a pressure transducer.

  • Pressure sustaining valves: They are used to control an upstream pressure from the valve using a pressure transducer.

  • Flow limiters: The purpose of this type is to regulate the flow rate of the pipe monitored by a transducer.

  • Tank level controllers: Using a level sensor, the capacity of a tank can be controlled.

  • Elevated tank level controllers: The control valve can also be used to manage the level of an elevated tank.

What control valves do we typically design and manufacture at Valfonta?

At Valfonta, we are specialists in pressure reducing and relief valves. We have been designing and manufacturing these components for all types of fluid systems for many years. We started working in 1962 and, over time, have expanded and improved our valves to become a leading reference in the industry. Today, we have a broad catalog of pressure reducing, relief, or excess pressure valves, and we have also dedicated a significant part of our effort to the development of control valves with pneumatic actuators. On the other hand, we also design custom-made valves for each client. We work for various sectors and export our products throughout the country.

FAQ’s

A control valve is a device used to regulate the flow, pressure, or temperature of a fluid within a piping system. It works by adjusting the opening of its internal passage, allowing precise control of the fluid.

The main types include globe valves, butterfly valves, ball valves, pressure reducing valves, pressure sustaining valves, flow limiters, and level controllers for tanks and elevated tanks.

It is crucial to consider the resistance to the fluid’s temperature and pressure, the appropriate size for the flow rate, and the capacity to withstand erosion or corrosion.

Valfonta specializes in pressure reducing and relief valves, as well as designing control valves with pneumatic actuators and custom-made valves for various sectors.
