Advantages of Electric Control Valve

High Accuracy and Repeatability

Electric control valves enable precise flow control, which is important for applications that require tight control of process parameters. Repeatability ensures the consistency of each operation, which allows the experimental and production process to remain stable.

Security

By reducing manual intervention, electric control valves reduce operating risks, especially in hazardous or toxic environments. The electric control valve can be equipped with a complete safety system, such as an emergency shutdown function, to further improve safety.

Maintenance

Electric control valves have fewer moving parts, reducing the possibility of wear and failure, thereby reducing maintenance needs and costs. Some electric control valves also have self-diagnostic functions to detect and report potential problems for timely maintenance.

Lower Operating Costs

Electric control valves are generally more energy efficient, especially in applications that require frequent switching or flow regulation. By reducing maintenance and increasing efficiency, electric control valves help reduce overall operating costs.

Types of Electric Control Valves

01/

Electric Globe Valve: Offers precise flow control for applications requiring accurate regulation of flow rates, such as HVAC systems or process industries.

02/

Electric Ball Valve: Ideal for on/off control applications requiring quick operation and tight shut-off, commonly used in water treatment, chemical processing, and industrial automation.

03/

Electric Butterfly Valve: Suitable for applications requiring efficient flow throttling, with a compact design and low-pressure drop, commonly used in HVAC, water distribution, and process industries.

04/

Electric Plug Valve: Used in applications requiring tight shut-off and minimal leakage, with a tapered or cylindrical plug controlling flow through the valve, commonly found in oil and gas, petrochemical, and refining industries.

Application Scenarios

Chemical industry

Electric control valves can be used in various chemical processes, such as reactor control, mixture modulation, pipeline transportation and other scenarios.

Power industry

Applied to steam turbine, boiler and other equipment, water vapor control, fuel supply and flue gas regulation and other processes.

Water treatment industry

In sewage treatment, water supply and other water treatment systems, control water flow, water pressure and water temperature.

Petrochemical industry

In the oil, natural gas transportation and storage process, control the flow of fluid media, pressure and temperature.

Pharmaceutical industry

Electric control valve can meet the requirements of the pharmaceutical process on the fluid flow parameters.

Food and beverage industry

In the food and beverage processing, the liquid flow, temperature and pressure control.

Important Parts of the Electrical Control Valve

T Valve Body: This includes the valve body that is holding the flow passageway and the valve plug or ball.

Valve Trim: Valve trim refers to the valve plug or ball, seat, and all the inner parts with which fluid comes into contact.

Actuator: This is the portion of the valve that receives an electrical signal and transforms electrical energy into mechanical energy in an attempt to position the valve plug or ball.

Positioner: This provides feedback control, meaning it maintains the valve plug or ball at a given position. The actual valve position is compared with the set valve position, and corrective signals are sent to the actuator.

FAQ

Q: Which voltage of the electric actuator?

A: DC24V, AC24V, AC110V, AC220V AC380V can be customized and DC12V is available for some smaller torque of actuator.

Q: What is the actuation time for electric actuator?

A: It depends on the torque of actuator. The detailed timing would be as the following:
·COVNA-05(50Nm)-20 seconds
·COVNA-10(100Nm)/COVNA-16(160Nm)-25 seconds
·COVNA-30(300Nm)/COVNA-60(600Nm)-60 seconds
·COVNA-125(125Nm)/COVNA-250(2500Nm)/COVNA-400(4000Nm)-100 seconds.

Q: Can the actuation time be faster?

A: Electric actuator can be customized the quick actuation gear, the soonest actuation time can be reach 10 seconds to open and close.

Q: What type of electric actuator you provide?

A: ON/OFF type, Regulation type and Intelligent type.

Q: Have the electric valve had the limiting operating time?

A: Electric haven't had the limiting operating time. It can be working for 99 hours continually without getting heating.

Q: Can this electric valve be resettable (normally open / closed) automatically when power is removed?

A: Our regular electric actuator can't be resettable automatically while power-off. But it can go to the multiturn electric actuator model with the extra electrical storage device along, which acheieve the valves can be automatic reset(normally closed) while power failure.

Q: Have the electric actuator had the presence of limit switches (contact about the position of the cut-off device)?

A: Yes, there is the position indicator on the top of actuator. The open/closed status can be checked visually.

Q: Which type of protection class of this electric actuator?

A: IP65, IP68, Explosion proof.

Q: Is there any manual override of electric valve?

A: Yes, every electric valve includes the manual override. You can open/close
