High pressure check valve

High pressure check valve

Check Valves are designed for a pressure range from 20 MPa to 70 MPa especially for conditions in chemical and petrochemical industry. Only forged material is used for high pressure equipment.


Design:

  • with hollow cone, check cone, plate
  • with straight through for vertical and horizontal installation
  • angle or straight through type (vertical installation of the check cone)
  • with steam jacket
  • different connections (threaded flanges, welding ends, welding neck flanges, connections according customer specification...)
