Check Valves

These durable valves are a combination of stop valve and check valve. Valves open wide for full flow in the direction of the arrow shown on the valve body and promptly shut when reverse flow occurs. These stop cum check valves are socket welded type and are directly welded to the steel piping, eliminating potential leaky flange joints. These valves are ideal for liquid pump and compressor discharge applications. Their design makes them particularly well suited for small package equipment and compact assemblies where space may not be available for two separate valves.
  • Port size - 1" - 6"(25mm to 150mm)
  • Available in angle way and straightway versions
  • Avoids separate check valve
  • Use of these combination valves reduces pressure drop
  • Minimise space requirement
  • Simplifies installation
  • Easy to dismantle for examination and maintenance
  • Valve cone has a built in flexibility to ensure tight and perfect closing with valve seat
  • Back seated type so that seal can be replaced while the valve is still operating
  • Designed to operate at very low differential pressure
  • Suitable for R717 (Ammonia), R744 (CO2) HCFC AND HFC
  • Safe working pressure 400 psig (27 bar)
  • Temperature range: -60° F to +240° F( -51° C to +116° C)
