Features

• Double flanged design.
• The flap is totally encapsulated in NBR rubber for superior sealing and corrosion resistance.
• The flap rises above the flowpath reducing wear and allows for a flushing action during operation.
• All iron components are coated in fusion bond epoxy resin.
• Top entry cover allows for easy access for cleaning and maintenance.
• Full flow design for less head loss, less debris accumulation and easy maintenance.
• Lower open pressure and excellent seal performance of low pressure.
• Simple construction with the flap the only moving part.
