Industries are increasingly converting their mechanical pumps to water- or steam-driven alternatives. That's because steam and water ejectors are much easier to install and are powered fully by their own motive gas or fluid. This key benefit makes water and steam ejectors much more efficient than mechanical pumps, reducing costs and improving system reliability for diverse industrial applications.
Valve actuators are mechanical devices that open and close valves to allow or stop the flow of a fluid through a system. They are available in many variations, each of which offers different advantages and disadvantages that make it suitable for distinct applications. Two of the most commonly used types are pneumatic actuators and electric actuators. Pneumatic actuators utilize compressed air to operate valves, while electric actuators use an electric motor. Below, we go more in-depth on the differences between the two to help readers choose the best one for their application.
Linear valve actuators are connected to a control valve to create motion that will perform the open/close valve operation. This motion can either be pneumatically or electrically generated, depending on the type of actuator in use. Some industrial processes may require electric linear actuators for precision valve control, while other processes employ pneumatic linear actuators which can rapidly execute valve operation.
