Product Description

Electric Soft Seal Flange Telescopic Butterfly Valve

Product Description

Telescopic butterfly valve is a type of valve that uses a circular butterfly plate as the opening and closing element and rotates with the valve stem to open, close, and regulate fluid channels. It is a component used to achieve on/off and flow control of pipeline systems.

Working Principle

Working Principle:

A telescopic butterfly valve is a type of valve that uses a circular butterfly plate as the opening and closing member and rotates with the valve stem to open, close, and regulate fluid channels. The butterfly plate of the telescopic butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical channel of the telescopic butterfly valve body, the disc-shaped butterfly plate rotates around the axis, with a rotation angle between 0 ° and 90 °. When it rotates to 90 °, the valve is fully open.

Product Features

Features:

1. Compact and lightweight, easy to disassemble and repair, and can be installed in any position.
2. The structure is simple and compact, with low operating torque and quick opening at 90 degrees of rotation.
3. The flow characteristics tend towards a straight line, with good regulation performance.
4. The connection between the butterfly plate and the valve stem adopts a pin free structure, which overcomes the possible internal leakage points.
5. The sealing components are replaceable and the sealing is reliable, achieving bidirectional sealing.
6. Butterfly plates can be coated with coatings such as nylon or polytetrafluoroethylene according to user requirements.
7. This valve can be designed for flange connection and clamp connection.
8. The driving mode can be selected as manual, electric or pneumatic.
