Approvals

WRASISO 9001

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

Description

The RDCV is a fully encapsulated resilient disc seat, double flange swing check valve for reliable reverse flow prevention, suitable for clean water and sewage applications. The 40-degree angle declined seat enables quick closure and minimises water hammer and slamming. The rubber disc is totally encapsulated in NBR rubber for superior sealing and corrosion resistance, with nylon fabric reinforcement to prevent cracking during operation.
