A-type Clamp Butterfly Valve

A-type clamp butterfly valve is a butterfly valve installed through clamp flange connection, adopting a medium line design, and the valve plate can rotate 90 ° for rapid opening and closing. Its structure is compact and lightweight, suitable for low-pressure and low-temperature ordinary media (such as water and air), relying on rubber or soft seals to achieve basic cutoff function. It has the characteristics of economic practicality and easy maintenance, but cannot meet the requirements of high-pressure, high-temperature or highly corrosive working conditions.

Economy and easy maintenance

Economy and easy maintenance
01
The number of components is small (only core components such as valve body, valve plate, sealing ring, etc.), and there is no need to disassemble the pipeline during maintenance, making it easy to replace the sealing ring.

Multi station installation adaptability

Multi station installation adaptability
01
The centerline design is achieved by welding the valve body with short structural steel plates, which is not limited by the flow direction of the medium and supports vertical or horizontal installation.

Low flow resistance and high flow efficiency

Low flow resistance and high flow efficiency
01
The straight through flow channel combined with a medium line disc structure, with the valve plate thickness as the only resistance when fully opened, results in minimal pressure loss and is suitable for conveying high flow media.

Quick opening and closing with low operating torque

Quick opening and closing with low operating torque
01
The 90 ° rotary valve plate design only requires a simple driving device to complete the opening and closing action, with small operating torque and fast response speed.

Compact structure and lightweight design

Compact structure and lightweight design
01
Adopting a clamp type flange connection eliminates the traditional flange structure, resulting in a smaller overall volume and lighter weight, making it easier to install in limited spaces.
