Most actuators come with a physical position indicator that shows the position of the valve and actuator; this may be in the form of a mechanical dial or on-screen indication. If the valve actuator is mounted to an additional gearbox, it often is supplied with a pointer cover to offer visual position indication. Many actuators have status relays available to the customer signaling actuator position, torque-fault, general fault, run indication or intermediate position. In the case of non-intrusive actuators, they will have relays that can be programmed to the customer’s desired feedback signal requirements. All the AME actuators have the possibility to choose either voltage input signal from the controller or current signal from the controller on a DIP switch. There is also an additional option to choose that the actuator either will work from the 0-10V or the 0-20mA signal from the controller.
Linear actuators consist of an electrical motor, reduction gears, travel limiting devices, an electrical enclosure, and valve stem drives. Control and positioning are extremely accurate with electric actuators. This type of actuator can be adapted to flexible processes and is inexpensive to operate. Thus, a modern electric system is energy efficient and can save you money in many cases. When you compare electric valves and solenoid valves side by side, you’ll find there are four fundamental differences between the two. While these critical valves are very similar in function, they differ in their function, actuation, application, and processing capabilities.
Make sure the actuator is supplied to match the controls available at site. An actuator may be supplied with a device to place it in a safe position. This device often uses a spring or other technology to place the actuator in the defined safe position. Highly efficient axial fans controlled by VLT® HVAC Drive FC 102 at Volkswagen Navarra, Spain, delivered 20% energy savings in AHU operation. Thanks to easy selection, installation, commissioning and maintenance, Danfoss MCVs simply cost you less time, money and effort.
The ball is available with a number of standard angle cuts, the patent-pending “Batwing” cut for linear control, and custom patterns for unique applications. Available in a variety of sizes and materials, the Series EBVA actuator with 4-20 mA can be added in the field if you want to upgrade to electronic control. Available with premium heavy-duty shut-off valves or True Blue ball valves. Commonly, the failure modes of actuators are achieved as either fail open or fail close. For the design to achieve a specific failure mode, the following two combinations of the valve body and actuator combinations are used. These are intended for low to high-cycle applications that require a power outage failsafe and compact design.
When selecting the type of actuator, if the torque of the actuator is too small, the valve cannot be opened and closed normally. Therefore, the electric actuator must select a reasonable torque range. The output torque of the electric actuator should be 1.2 to 1.5 times the maximum torque of the valve operation.
The linear type is perfect for globe, gate, angle, and diaphragm valves. Motor speed – Faster motors guarantee a quick response to input signals when dealing with fluid modulating service. While fast actuator response is critical, it affects the stability of the electric actuators. A quick-acting actuator is likely to overshoot beyond its operating limit. Solving this problem requires the use of a motor with lower revolutions per minute. Alternatively, a speed reduction mechanism will facilitate a perfect balance between stability and responsiveness.
For example, airports use them for de-icing aircraft, greenhouse managers use them forwatering greenhouses, and farmers use them forwatering large farms. Buildings with fire suppression technology rely on ball valves for opening and closing the sprinkler heads. The Spirax Sarco range of piston actuated valves provide a competitive solution for on/off control applications by combining many key benefits in each valve. These elements sustain a product that encompasses a wide range of industrial applications. Spirax Sarco’s state-of-the-art control valves are available to suit almost every application. Designed to provide accurate, repeatable performance with the utmost reliability.
The biggest difference between electric and pneumatic actuators is the driving force of their operation. The motor, when supplied with voltage, engages a gear train which produces the torque necessary to cycle the ball valve. Torque is the rotational force an actuator generates to close a rotational valve. Electric actuators can generate this force by transmitting it to the output shaft and then the valve stem. When van kitz is applied to the valve stem, the valve’s orifice opens or closes. The straight flow is inverted S flow, the flow path is complicated, and the upper and lower chambers have many dead zones, which provide a place for the precipitation of the medium.
