How Motorized Valve Actuator Work
The motorized rotary valve actuator is an electromechanical equipment used for remote control of rotary valves (such as ball valves and butterfly valves). Compared to pneumatic and hydraulic actuators, electric valve actuators provide a more energy-efficient, cleaner, and quieter valve control method. We sell the packaged sets together with the valve or a separate actuator and added to existing valves.
Motorized Valve Actuator Parameters
Motorized rotary actuators convert electrical energy into rotational force, rotate 90 degrees. The electric motor provides torque, which is transmitted to the valve through motor shaft. The motor voltage options are AC, DC, or one of them. The motor is installed in a compact housing, which also includes other components of the actuator, such as gears, limit micro-switches, PCB, etc. The whole actuator is connected to the valve through a compatible connection interface, such as ISO 5211 standard.
Rotate Torque
A valve needs to be rotated 90 ° to fully open or close. To rotate the valve, torque is required. The electric actuator generates this torque and transmits it to its output shaft, which is connected to the valve stem or shaft. This in turn rotates the ball or disc of the valve, opening or closing the orifice to allow or block flow. The torque of the actuator depends on its transmission device and motor's power. The motor torque is an important specification of the actuator, as it requires a torque higher than the valve's required to ensure that the valve can be opened and closed. Usually, the breakaway torque is specified as the required torque for the valve, as this is the highest torque required to rotate the valve.
Starting Torque(Breakaway Torque)
When the valve is in the open or closed position, the torque requires the starting torque to move the valve from a stationary position. Normally, the breakaway torque is bigger than the run torque. For example, the starting torque of a regular ball valve is about 30% higher than its run torque. The higher starting torque is due to its stationary position, where the medium may accumulate in the ball cavity and/or scratch the valve seat, resulting in increased friction, etc. A valve actuator should generate a torque higher than the valve starting torque.
Response Time
The response time is the time required for the actuator to rotate the valve a full 90 degrees (i.e. fully open or close the valve after issuing a command). Like torque, the speed of the actuator is related to gears and motor. The torque and speed of the actuator are directly related, as torque is inversely proportional to speed. This relationship is influenced by the gears' design. For a given actuator motor capacity, a higher gear ratio will result in more torque and slower response time compared to a lower speed ratio. Therefore, if response time is a critical application specification, it needs to be considered together with torque specification requirements.
Control Method
The motorized valve actuators have either 2-wiring control (commonly referred to as just on/off) or 3-wiring control.
Voltage
Electric actuators can be DC or AC voltage. The voltage ratings: 12V, 24V, 48V for DC and 24V, 48V, 110V, 220V for AC.
Mounting
The actuator has a connection interface that connects them to the valve. This includes an output driver, a square shaft or stem connecting the valve head, and a flange connecting the actuator bolt to the valve. The design and size of this connection interface can be brand specific or standardized, such as ISO 5211. Figure shows the ISO 5211 flange type of valve. Regardless of the brand, different valves and actuators can be interchangeable as long as they follow the same ISO 5211 standard. According to the ISO 5211 standard, there are different flange types that vary depending on the maximum flange torque, size, and number of screws, bolts, or studs.
Electric Valve Actuator Features
Position Indicators
The position indicator indicates the open or closed position of the actuator at a given time. There are visual indicators, but there are also electronic position feedback systems that send the position back to your system (i.e. controller). The position indicator can only display the basic open and closed positions, or it can also indicate partially open or partially closed.
Manual Override
Manual override is a safety design in most actuators. It is usually a mechanical handwheel or handle. This wheel allows you to mechanically close or open a valve in case of power failure or any other emergency.
Limit Micro-Switches
Limit micro-switches are the electromechanical components of the actuator, which include a closed limit switch cam and an open limit switch cam. When the actuator moves the valve to the open or closed position, the corresponding switch cam will also move. When reaching the end position, the corresponding switch cam cuts off the power. To prevent further movement and provide restricted seating. Extreme valve seat refers to keeping the valve in the desired end position. In some actuators, the limit switch cam is adjustable. This allows you to set a position as the end position, such as 50% open. The limit switch cam can be incorporated into the position indicator as a mechanical linkage between the valve and the actuator.
Duty Cycle
The duty cycle specifies the usage time of an actuator between cycles. The valve opening to closing makes one cycle. The duty cycle is a cycle of on-time to off time, expressed as a percentage. It is calculated using the formula below. An example would be if it takes an actuator 5 seconds to open, 8 seconds to close, then 10 seconds to rest after opening and closing, the duty cycle would be (5+8 / 5+8+10) × 100 = 56.5%.
(opening time + closing time) / (opening time + closing time + rest time) × 100% = duty cycle
Fail-Safe
Fail-safety is designed to close or open valves in the event of a power failure. Fail-safety is an important safety function of some automatic valve actuators.This kind of system requires a energy storage, such as a spring mechanism or battery. Normally, the fail safe mechanism close the valve. In the spring mechanism, when the power is cut off, the loaded spring will automatically close the valve. For backup battery systems, commonly referred to as Battery Safety Loop , the battery provides power to the actuator to shut it down. The charging time and total speed may vary depending on the size of the battery and actuator. In order to obtain additional redundancy, some actuators will include two versions of fault protection in their design. As mentioned earlier, most fail safe operations will close the valve, but some applications require the valve to be opened in the event of a power failure. An example of this application is the cold water flow entering the heat exchanger. This is because cold water is needed to cool the remaining warm fluid to prevent overheating.
Modulation
Some electric valve actuators have the ability to perform modulation control, which is commonly referred to as Digital Positioning System. This is the ability to accurately position the valve at any point between fully open and fully closed (between 0 ° and 90 °). This is necessary for applications that require changing the flow rate. Typically, modulation is achieved using a control loop system and a positioning circuit board (PCB) placed in the actuator.
Electrical Wiring
The optional wiring could be chosed, like 2- and 3-wiring actuators. Before installing, verify that the actuator code matches the connection diagram. Improper installation can permanently damage the actuator or lead to dangerous situations. The actuators have internal position switches, which results that only energy is consumed during opening or closing.
2-Wiring Control DC/AC Actuator
Spring return in case of the power is failure
SW Close, the valve is opened, the actuator automatically power off after in place
SW Open, the valve is closed, the actuator automatically power off after in place
Voltage: AC110V~230V, DC12~24V
3-Wiring Control DC/AC Actuator
RD Connect with positive, GR connect with SW and positive
BK connect with negative
When SW of GR closed, the valve OPEN, the actuator automatically power off after in place, remian the closed position
When SW of GR opened, the valve CLOSE, the actuator automatically power off after in place, remian the closed position
Standards
IP Protection Grade (IEC 60529)
Motorized valve actuators have a protection class IP (ingress protection) rating. The IP rating specifies the actuator's protection against dust, water, and other environmental hazards. Over IP 54 rating of ball valve actuators can be partially protected from dust and can resist water spray.
Duty Type (IEC 60034-1)
This is an international IEC (international electro-technical commissions) standard for rotating electric devices. For electric actuators, it specifies the duty type and duty cycle of their electric motors. An actuator rated S2 30min can continuously operate short-time duty for 30min after which the motor should be allowed to rest. It can be restarted after its temperature has returned to room temperature.
Low Voltage Directive (LVD) 2014/35/EU
The LVD certification ensures that low voltage electrical equipment, such as actuators, provides sufficient protection for its users.
Electromagnetic Compatibility (EMC) 2014/30/EU
An EMC-certified actuator neither generates nor is affected by electromagnetic disturbance.
Material
