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.
