Features:
Signal butterfly valve is a throttling device, suitable for high-rise building fire protection systems and
other pipeline systems that need to display the valve switching status.
1. Small and lightweight, easy to disassemble and repair, and can be installed at any position.
2. The structure is simple and compact, and the 90° rotation opens and closes quickly.
3. The operating torque is small, labor-saving and lightweight.
4. Achieve complete sealing, and the gas test leakage is zero.
5. Choose different parts materials and be applicable to a variety of media.
6. The flow characteristics tend to be linear and the adjustment performance is good.
7. The number of opening and closing tests can reach up to 10,000 times and the service life is long.
