Product Features

  • Nozzle check valves with bodies notably larger in diameter than their inlets display the best flow characteristics.
  • The disc faces for all of our nozzle check valves are designed to maximize hydrodynamic efficiency and minimize pressure loss.
  • All nozzle check valves, feature soft seats, and a specially designed and sourced O-ring installed in the seat of the valve. A soft seat drastically reduces reverse flow leakage and aids the quiet closing of the valve.
  • Nozzle check valves use only one spring designed for a million-cycle lifetime in the body, as opposed to most other
    companies, which use multiple springs. Minimizing the number of springs reduces the potential for failure.
  • Long service life, with the minimum level of maintenance requirement.
  • Suitable for horizontal and vertical installations.
  • Minimizes water hammer effect in the system
  • Directional application, please check the arrow mark on the body for the correct direction
  • Flange connections according to EN1092-2 / ISO 7005-2.
  • Hydrostatic test pressure for the seat: PN x 1.1 (e.g.: PN 16 = 17.6 bar); for shell: PN x 1.5 (e.g.: PN16 = 24 bar) according to EN 12266-1.
