Valves and Actuators

Valves and Actuators,

the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. Power-operated actuators, using gas pressure, hydraulic pressure, and electricity, allow a valve to be adjusted remotely and allow rapid operation of large valves. A manual actuator employs levers, gears, and wheels to move the valve stem. Manual actuators are powered by hand. Manual actuators are inexpensive, typically self-contained, and easy to operate. A valve actuator is a mechanical device that uses a power source to operate a valve. This power source can be electric, pneumatic Levers on extensions for hard to reach valves or valves with extremely hot or cold media running through them.

A valve is a device or natural object that regulates, directs, and controls the flow of fluid gases, liquids, fluidized solids, and slurries by opening and closing partially obstructing various passageways. Valves are technically fittings.

An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a mover and the actuator requires a control signal and a source of energy.

Control valves need actuators to operate. This tutorial briefly discusses the differences between electric and pneumatic actuators, the relationship between direct acting and reverse acting terminology, and how this affects a valve’s controlling influence. Valve actuators are selected based upon a number of factors including torque necessary to operate the valve and the need for automatic actuation. The differential pressure across the diaphragm positions the valve stem. Automatic operation is provided when the air signals are automatically controlled by circuitry.
