Wafer Remote Control Butterfly Valve with Fire Fighting Signal

Short Description:

Signal butterfly valve is a center line type butterfly valve, it has the advantages of simple structure, reliable seal, light opening, long life, easy maintenance and so on. Therefore, it is used in water supply and drainage, building fire fighting system and other pipelines, especially in the fire fighting pipeline. The signal valve can clearly show the valve switching state, has an intuitive, clear, reliable reflection of the working state of the fire fighting system, so, a large number of suitable for fire fighting system.

1. Fire signal butterfly valve is small and light, easy disassemble and maintenance, can be installed in any position.

2. Fire signal butterfly valve with compact structure, 90 degree operation open and close quickly.

3. Fire signal butterfly valve with small operating torque, easy manual operation.

4. Fire signal butterfly valve can achieve complet sealing, zero leakage and perfect performance.

5. Fire signal butterfly valve can feedback its open/close state clearly to fire protection system, so it is widely and widely used in the fire protection system.

    Advantages of a Butterfly Valve

    Butterfly valves are similar to ball valves but have more advantages. They are open and close very quickly when actuated pneumatically. The disc is lighter than a ball, and the valves require less structural support than a ball valve of comparable diameter. Butterfly valves are very precise, which makes them advantageous in industrial applications. They are quite reliable and require very little maintenance.

    1. Turning on/off easily and rapidly with less force. Having less fluid resistance and can be operated frequently.

    2. Simple structure, small size and short face to face dimension, which suitable for large diameter valves.

    3. It can be used for transmitting mud, fewer liquids are stored at apertures of pipe.

    4. Long service life. Standing the test of tens of thousands of opening/closing operations.

    5. Butterfly valves have excellent regulation performance.

    6. Small torque. The pressure on discs at the two sides of the spindle is almost equal, causing contrary torque. Thereby, the valves can be opened with less force.

    7. Sealing face is generally med of rubber or plastic. So the butterfly valves can be with good sealing under low pressure.
