Flange butterfly valve uses and characteristics

When the flange butterfly valve is in the fully open position, the thickness of the butterfly plate is the resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics.

Flanged butterfly valve seal structure using PTFE, synthetic rubber composite valve seat, which is characterized by the elasticity of the valve is still provided by synthetic rubber and the use of PTFE low friction coefficient, not easy to wear, not easy to aging characteristics, so that the life of the butterfly valve can be improved.

The flange butterfly valve has the same sealing principle and structural characteristics as the ordinary medium type butterfly valve.

characteristic

Compact and lightweight, easy to disassemble and repair, and can be installed in any location.
Simple structure, compact, small operating torque, 90° turn open quickly.
The flow characteristic is linear and the adjustment performance is good.
The connection between the disc and the valve stem is made of a pin-free structure to overcome possible internal leakage points.
The outer circle of the butterfly plate adopts spherical shape, which improves the sealing performance and extends the service life of the valve, and maintains zero leakage with pressure opening and closing more than 50,000 times.
The sealing parts can be replaced, and the sealing is reliable to achieve bidirectional sealing.
The butterfly plate can be sprayed with a coating, such as nylon or PTFE, according to user requirements.
The valve can be designed with flange connection and clamp connection.
The driving mode can be manual, electric or pneumatic.

Flange butterfly valve is suitable for temperature ≤120℃ or ≤150℃, nominal pressure ≤1.6MPa water supply and drainage, sewage, food, heating, gas, Marine, hydropower, metallurgy, energy systems and textile and other industries, especially suitable for bidirectional seal and valve body easy corrosion occasions, as regulating flow and cut-off medium.
