Key Features:

  1. Manufactured from high-grade Ductile Iron for excellent strength and durability
  2. Dual plate / double door design with spring-assisted closure for quick response
  3. Wafer type body for easy installation between two flanges (no additional gaskets required in most cases)
  4. Resilient seated (EPDM / NBR) or metal-to-metal seating options
  5. Available in PN 10, PN 16, PN 25, PN 40 and higher pressure ratings
  6. Epoxy coated or fusion bonded epoxy (FBE) inside and outside for superior corrosion protection

Main Advantages:

  1. Extremely compact and lightweight compared to traditional swing check valves, saving space and installation cost
  2. Spring-assisted dual plates ensure rapid closure, minimizing water hammer and reverse flow
  3. Low pressure drop due to streamlined flow path
  4. Suitable for both horizontal and vertical installations (flow direction dependent)
  5. Easy maintenance with no need for special supports in most pipeline configurations
  6. Ideal for pumping stations, HVAC systems, water treatment plants, and industrial applications where space is limited
