Features
- Double flange design with a disc composed of a ductile iron plate, stainless steel bar shaft and nylon-reinforced fabric
- Rubber disc totally encapsulated in NBR rubber for superior sealing and corrosion resistance
- Nylon fabric reinforcement prevents disc cracking and breaking during operation
- 40-degree declined swing seat enables quick closure and minimises water hammer and slamming
- Shorter stroke reduces water hammer; flap disc rises above the flow profile to reduce wear
- All iron parts coated in fusion-bonded epoxy resin
- Top-entry cover allows access for cleaning, replacement and maintenance
