Fire Protection Wafer Type Butterfly Valve

The wafer type butterfly valve is a compact, lightweight flow control valve designed for fire protection systems. It installs between two flanges and is operated by a handle or gear actuator for rapid open/close switching.

Key Features & Advantages

  • The self-sealing center-line butterfly valve is a newly designed and innovative valve with a micro-interference between the rubber disc and valve channel, which can decrease abrasions to the sealing face, increasing the service life of valves.
  • With a self-sealing structure, the sealing property of the butterfly valve is proportional to fluid pressure, allowing the valves to withstand high pressures.
  • The sealing lip on the rubber disc can remove mud and dirt when the valve closes.
  • The outer and inner surfaces of the wafer valve are coated in a high quality epoxy powder, so the paint coat is complete and even, making the valve safe for use in the food, beverage and pharmaceutical industries.
