Check / Non-Return Valves

PDF version

Hale Hamilton's standard NR & NRS ranges of in-line non-return valves feature a mitre seat with ‘o’-ring insert to ensure a leak-tight shut-off with an efficient flow path. The valves are but lightly spring loaded to enable positive operation at any angle of installation.

Available in either hard or soft seat, this range of non-return valves has been developed for use within high pressure gas & liquid  applications. Adiabatically shock tested variants are available to EN ISO 7291.

  • Series NRS are a range of soft seated valves available in orifice diameters ranging from 6 to 25mm, with port connections ranging from G1/4" to G1 1/4". Body materials of Brass, Aluminium Bronze, Stainles Steel, Monel & Inconel with a maximum working pressure of 414bar.
