Focus on Actuation
Focus on Actuation
From October this year Valves Online will be moving into our new purpose built industrial unit in Yelverton (just outside of Plymouth), known as 'The Innovation Centre'.
As well as holding a large stock of manual valves the site will be equipped with a specialised state of the art valve/actuator build and test department, supplying the best in pneumatic and electric actuated ball, butterfly, knife gate and many more valves used in numerous industries throughout the South West.
Used for the automation of industrial valves, actuators can be found in all kinds of process plants such as wastewater treatment plants, power plants, refineries, mining and nuclear processes, food factories, and pipelines. Valve actuators play a major part in automating process control. Automated valves vary both in design and dimension and Valves Online cater for all applications.

Actuation
A valve actuator is 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 allow a valve to be adjusted remotely or allow rapid operation of large valves.
Electric Actuated Valves
Electric actuators are generally designed to operate ball valves and butterfly valves at controlled rates of opening. The electric actuator uses an electric motor to provide torque to operate a valve. They are quiet, non-toxic and energy efficient, can also operate on batteries.
Pneumatic Actuated Valves
Air (or other gas) pressure is the power source for pneumatic valve actuators. They are used on linear or quarter-turn valves. Air pressure acts on a piston or bellows diaphragm creating a linear force on a valve stem. Alternatively, a quarter-turn vane-type actuator produces torque to provide rotary motion to operate a quarter-turn valve. A pneumatic actuator may be arranged to be spring-closed or spring-opened, with air pressure overcoming the spring to provide movement. A "double acting" actuator use air applied to different inlets to move the valve in the opening or closing direction. A central compressed air system can provide the clean, dry, compressed air needed for pneumatic actuators.
