COMBINING THE BEST OF TWO WORLDS (Single Spring & Ring Disk) SPECIFICALLY FOR GAS SERVICE


NZ is designed for the gas applications with very low flowrates; it combines the advantages of minimized friction due to zero bending moments on the disc, stable operation at partial open flow and best dynamic behavior due to shortest disc stroke of any axial check valve. Type NA is in accordance with API face-to-face dimensions.

Materials according to customers request, such as Low Temperature Carbon Steel, Nickel-Aluminium-Bronze, Duplex, Superduplex, 6Mo, etc.


Features:

  • Fully Balanced Ring Disc

  • Single Spring

  • Specifically for Gas Applications

  • Worldwide Patented Design

  • Low Pressure Loss

  • Maintenance Free

  • Easily Adjustable on Site

  • 12" - 88" (DN 300 - DN 2200)

  • Up to PN400 (ANSI 2500)
