What Is a Valve Actuator? To operate a valve, you need a valve actuator. The valve actuator works as a power source for the valve.There are two ways you can control an actuator. One, you can manually operate them using people.
A valve actuator isa mechanical device that uses a power source to operate a valve. This power source can be electric, pneumatic (compressed air), or hydraulic (the flow of oil). There are two main types of actuators, one for each of the two main types of valves that require them. The...
The main parts of a globe valve are the actuator, stem, body, disc, seat, bonnet and some form of sealing arrangement (packing).The disc seats at a right angle on the seat surfaces and this generally yields a better sealing arrangement compared to gate valves. As the disc is lowered ...
valve (very easy to do), then a retaining ring on the bottom of the actuator must be removed (requires retaining ring pliers). The pinion shaft is then pushed out from the top, rotated 180º, then re-inserted. The actuator will then act upon the valve opposite the way it did ...

manual opening, but then has automatic shutoff via a float. An example of an industrial valve is an air-actuated ball valve with a limit stop; it requires an external force (compressed air to the actuator) to open, but then stops automatically depending on where the limit stop is set. ...
A ball valve is a rotational motion valve that uses a ball-shaped disk to stop or start fluid flow. The ball, shown in Below Figure, performs the same function as the disk in the globe valve. When the valve handle is turned to open the valve, the ball rotates to a point where the...
