Manual Valve Vs Automated Valve

In today’s extremely automated industrial cleaning equipment depends heavily on valves remotely actuated either by a qualified operator or by an automated computerised control system. However performing predominantly the same function as manually operated valves, automated valves operated by electricity, air, hydraulics or some other means are considerably different than manual valves not only in their design but their function of operation as well. Identifying an automated valve for a specific application often challenges the systems engineer to take several views into consideration that wouldn’t be of importance if he were specifying a manual valve.

It would seem straightforward to automate any of the manual valves, as it makes sense to do so. All you would need to do is add a small motor or some other type of actuator to replace the operator. Actually, this was probably how older model automated valves were constructed.  It’s easy to imagine a motor with a              suitable speed reduction device managing the shaft of a globe valve.  Furthermore, however, there are complications like somehow knowing when enough rotation has been attained to either open or close the valve which could be a very complicated controls issue.  A ball valve, needing only a quarter turn might be a bit simpler but swapping the ball valve to a piston valve requiring only a simple linear motion is a very simple option and some automated valves are designed in just that way. Solenoids are straightforward and do a brilliant job of providing linear motion.
