Buy Valve electronic actuators

The hydraulic actuator is a double acting cylinder. The standard supply pressure for the hydraulic cylinder is min. 150 bars. The final cylinder size is determined according to the line pressure.
The standard cylinder is equipped with a pilot operated check valve which keeps the valve in position when hydraulic pressure is not available. Hydraulic actuator with electro-hydraulic actuators positioners (HP) is for demanding flow control the hydraulic actuator can be delivered with electro-hydraulic positioners. The standard incoming signal for the electro-hydraulic positioners is 4-20 mA. The hydraulic rotary actuators has the various features such as Analogue and digital communication, Speed, position, and acceleration control, Very high resolution capability, Local closed loop control of Temperature , Position Pressure and Flow. The valve electronic actuators has the ability to sense at the source, and provide reliable control, either in an independent standalone environment, or as an integral part in PLC plant systems. Depending on the application, butterfly and rotational valve control can be significantly enhanced.

As fuel costs rise and clean air regulations become more stringent, it becomes increasingly important to operate with maximum efficiency and greater reliability. Accurate, repeatable and reliable positioning of dampers, fluid couplings and valves are means to overall plant efficiency. Without accurate, responsive and repeatable actuation of final control devices, state-of-the-art controllers and control systems are useless. Hydraulic rotary vane actuators offer you a way to achieve tighter process control and eliminate the need for problematic instrument air systems.


A hydraulic actuator is a type of double acting cylinder, most of which have a standard supply pressure of no less than 150 bars. The line pressure is what will determine the final size of the cylinder that will be used. When determining the final size of the cylinder that will be used in a hydraulic actuator, it all comes down to the line pressure. When hydraulic pressure is not available, the valve on a standard hydraulic actuator is held in position by an equipped pilot operated check valve. The hydraulic actuator can, if necessary, be delivered with electro-hydraulic positioners. These electro-hydraulic positioners may be necessary if the flow control is demanding beyond normal levels. Electro-hydraulic positioners on a hydraulic actuator typically receive an incoming signal of anywhere from four to 20 mA.

One variety, known as a hydraulic rotary actuator, has various features not typically found in other models. These hydraulic rotary actuators have speed, position, and acceleration controls, and are capable of achieving very high resolutions. They also allow both analog and digital communication types, and have a local, closed loop of flow, position pressure, and temperature control. The valve's electronic actuators can actually sense directly at the source. This allows them to provide more reliable controls in any environment, from playing a core role in a PLC plant system to an independent, standalone environment. Depending on the situation and how they're applied, these highly versatile hydraulic rotary actuators can also significantly enhance the control of both butterfly and rotational valves.

As time goes on, the cost of fuel is steadily increasing, and clean air regulations are becoming more and more strict. We in the HVAC industry must work to maintain steadily rising standards. In this ever-changing environment, operating as reliably and efficiently as possible is becoming increasingly important. An entire plant's efficiency may suffer if dampers, valves, and fluid couplings aren't consistently positioned in an accurate and reliable manner. Even state of the art controllers and control systems can be rendered useless if the actuation of the final control devices is done inaccurately, or isn't 100 percent repeatable. With error control so vital to system maintenance, a hydraulic rotary vane actuator can be a valuable investment. Hydraulic rotary vane actuators are capable of tightening process controls. While instrument air systems can be problematic to work with, hydraulic rotary vane actuators may render them completely unnecessary.
