One. Product Overview

Middle line soft seal butterfly valve is the pipeline preferred conventional butterfly valve, with simple structure, small flow resistance coefficient, flow characteristics tend to straight line, will not stay debris. And the advantages of light weight, easy installation, small driving torque. This valve can be used to cut off the medium and adjust the flow of the medium. According to user requirements, the driving device can be manual, electric, pneumatic and other ways. Parts of different materials and sealing rings of different materials are selected to adapt to different media and working conditions, so as to achieve the best results in cost and performance. Soft seal butterfly valve is suitable for temperature ≤120℃, nominal pressure ≤ 1.6mpa water supply and drainage, sewage, food, heating, gas, ship, hydropower, metallurgy, energy system and textile industries, especially for two-way sealing and valve corrosion occasions, as flow regulation and closure medium.

Two, product features

1, small and light, easy disassembly and maintenance, and can be installed in any position.

2, simple structure, compact, small operating torque, 90° turn to open quickly.

3, the flow characteristics of straight line, good regulation performance.

4. The connection between butterfly plate and valve stem adopts no pin structure to overcome the possible internal leakage point.

5, butterfly plate outer circle using spherical shape, improve the sealing performance and prolong the service life of the valve, with pressure open and close more than 50,000 times still maintain zero leakage.

6, the sealing parts can be replaced, and the sealing is reliable to achieve two-way sealing.

7, butterfly plate can be spraying coating according to user requirements, such as nylon or ptfe.

8, the valve can be designed as flange connection and clamping connection.

9, the driving mode can choose manual, electric or pneumatic.
