How Many Control Valves Types Are There?

Control Valves

Control Valves that manage the flow from a fluid are the controls that regulate the flow. This publication explores the several types of valves that lessen the uncontrollable amount of flow, which are utilized in many businesses and organizations to prevent harmful pollutants from being produced. These valves may be used in different businesses such fuel refineries and agricultural plants for regulating variables like pressure, turbulent flow rate, temperature, PH balance, and level.

Types Of Control Valves Are There?

  1. Depending on the number of exits or routes
  • Two-way valves
  • Butterfly valve: A disc on a pole with open and close lever designed to move relatively small amounts of fluid. It does not regulate, open, and closes 1/4 of the way.
  • Pneumatically activated angle seat valve: They are used for opening or closing a passageway. They consist of stainless steel, and one of the primary advantages is that they require low maintenance, which significantly increases their life cycle. Like other ball valves, they are easy to install.
  • Covering a cone valve and utilizing a diaphragm action to close it are the reasons why cone valves tend to be used at low fluid pressures. Cone valves require a relatively strong actuator to keep that closure point caused by the device’s differential pressure, so that they are used when they are needed and liquid pressure is low.
  • Double seats: In these valves, the seats are put under pressure by both hydraulic mechanisms. These valves are usually used when the fluid pressure is very high.
  • Three-way valves (heating and air conditioning)

In these valves, the seats are subject to the hydraulic pressures of two different resonances. They are used when the hydraulic pressure is high.

  • Four-way valves

These valves are designed to regulate the temperature of a heating installation.

  1. Depending on the drive

The type of drive also varies manual, pneumatic, electric, etc.

  • Manually operated valves

In this case, the presence of an operator near the valve will be necessary.

  • Electrically or electronically actuated valves
  • The so-called electro valves or solenoid valves allow or close the passage of fluid when fed by an electric current, hence the name electro valves.

The solenoid valves can be of two types:

These valves are typically opened to prevent fluid from passing through them after an article is electrically powered. The valve will close, blocking a passage, and once we feed (a coil or solenoid makes the valve open and allows the passage of fluid).


Another sort of solenoid body is the one that is ordinarily open. Without the applying of an electrical current, the valve enables the fluid to flow. When we feed that solenoid valve with an electrical current, it closes the circulation of fuel through it. When that power stops, the valve opens up and again permits the gas to flow through the whole size of the body.


The controller necessary for the flow of fluids might be permissive depending on the intricacy of the setup.

  • Hydraulically or pneumatically actuated valves

A pilot determines the functioning of the hydraulic actuation valves. The internal controller contains pressure pads that correspond with the valve paths. The operators are essentially walking trails that move against the valves.


The structure of the slides used at Blackhawk Supply.com is to make a motion that traverses the tracks. The interplay between the tracks and fluid pressure is regulated by the fluid control valve.
