Электрический дроссельный клапан | Электрический привод | Корпус из ПВХ + Уплотнение EPDM | Ду50-Ду600 | Коррозионностойкий контроль потока

Product Overview

TheЭлектрический дроссельный клапан is a high-performance, electrically actuated flow control valve designed for reliable on/off and modulating service in water, воздух, газ, масло, chemical, and steam applications. Featuring a lightweight, corrosion-resistant PVC body with an EPDM seat, this valve provides excellent sealing performance, bubble-tight shut-off, and long service life in aggressive and corrosive environments. The electric actuator enables remote operation, precise positioning, and seamless integration with PLC, DCS, and SCADA control systems. Available in sizes from DN50 to DN600 with wafer or lug connections, this valve is ideal for water treatment, химическая обработка, ОВК, масло & газ, and industrial fluid control systems. With CE certification, OEM/ODM customization support, this valve is the trusted choice for engineers requiring reliable, automated flow control in corrosive media applications.

Принцип работы

The electric butterfly valve operates through an automated, precision-controlled mechanism:

• 1. Actuator Operation: The electric actuator receives a control signal (on/off, 4-20mA, or 0-10V) from the control system. The actuator motor drives the gear train, which rotates the valve stem.
• 2. Valve Operation: The stem rotates the disc 90° from fully closed (0°) to fully open (90°), with intermediate positions for modulating control.
• 3. Position Feedback: The actuator provides position feedback to the control system, enabling precise monitoring and control of valve position.

FAQ

1. What is the difference between an electric butterfly valve and a pneumatic butterfly valve?

An electric butterfly valve uses electrical power, requires no air supply, offers higher precision, and is suitable for applications without compressed air systems. A pneumatic butterfly valve offers faster response, better explosion-proof performance, and is suitable for hazardous areas with existing air supply. The choice depends on site power/air supply conditions and control accuracy requirements.

2. What is the difference between modulating and on/off electric actuators?

An on/off actuator provides only fully open or fully closed control, suitable for simple switching applications. A modulating actuator accepts 4-20mA or 0-10V analog signals for 0-100% precise position control, suitable for applications requiring accurate flow regulation.

3. What media is the PVC body suitable for?

The PVC body is suitable for water, сточные воды, воздух, газ, масло, химикаты, кислоты, щелочи, and mild chemicals. PVC offers excellent corrosion resistance but is not recommended for high-temperature (>80°С) or organic solvent applications.

4. What is the temperature range of the EPDM seat?

The EPDM (Ethylene Propylene Diene Monomer) seat operates from -10°C to +80°C. EPDM offers excellent resistance to water, weathering, озон, and aging, but is not recommended for petroleum-based oils or strong acids.

5. What is the protection rating of the electric actuator?

The standard protection rating is IP67, providing complete protection against dust and temporary immersion in water, suitable for outdoor installation and washdown environments. Higher protection ratings (IP68) are available upon request.
