HOW DOES A VALVE WORK WITH ACTUATORS
Valves are one of those critical inventions that go unnoticed by many. They play an important role in our world by controlling, regulating, guiding and directing the flow of assorted types of liquids, gases, steam or flowing materials such as mill, grain, etc.
Valves are made of steel, iron, steel, bronze or PVC and can handle high temperatures and pressure points. In certain applications, the velocity, which is controlled by the valve, is vital in the success of the system in which it is applied and can be manually controlled or automated. In every industry, there are various types of valves including ball, butterfly, v-port, solenoid, sanitary, knife gate, plug and many more. The following is just a few examples of where valves are critical in a particular application: sewage/waste water plant, dams that controls a body of water, valves in your vehicle that control gas flow or oil flow to your engine and oil and gas refinery companies.
Oftentimes, an actuator is attached to the valve to administer pressure control and flow control in applications where it is crucial that the actual value be the same as the set point value. This motor box is operated by pneumatic pressure or an electric current. It then changes this energy into motion which changes or moves the valve positioning in order to keep to the set point that was entered into the actuator by the operator.
