Shanghai Liangzheng ValveD971X-10SElectric Plastic Wafer Butterfly Valve

The electric plastic butterfly valve (also known as UPVC electric butterfly valve) integrates an electric actuator with a plastic butterfly valve. It can be directly controlled by a 220V power supply for on/off regulation, or it can be equipped with a built-in servo module, allowing operation via control signals (4–20mA DC or 1–5V DC) and single-phase power input.

The electric plastic butterfly valve (UPVC electric butterfly valve) is lightweight and corrosion-resistant, making it suitable for various applications, including pure water and drinking water pipeline systems, drainage and sewage pipelines, saline and seawater pipelines, acid, alkali, and chemical solution systems, among others. Its quality is widely recognized by users.

The main features of the butterfly valve are as follows:

1. Compact and aesthetically pleasing external structure.

2. Lightweight body for easy installation.

3. Corrosion-resistant with broad applicability.

4. Hygienic material composition.

5. Wear-resistant, easy to disassemble, and simple to maintain.

1. The valve adopts a centerline structure with excellent sealing performance.

2. The sealing pair consists of a UPVC disc and EPDM rubber, ensuring a long service life.

3. The rubber sealing ring can be mounted on either the valve body or the disc, making it suitable for media with different characteristics, providing users with options.

4. The disc features a frame structure with high strength, a large flow area, and low flow resistance.

5. Effectively resists corrosion, and by replacing the sealing seat material, it can be used for different media.

6. The valve offers bidirectional sealing functionality, with installation不受介质流向的控制 (unaffected by media flow direction) and不受空间位置的影响 (unaffected by spatial orientation), allowing installation in any direction.

7. The valve operates flexibly, with low effort and high convenience.
