NAF Check

Tilting disc check valve. Unique design gives excellent tightness and minimizes water-hammering.
  • The center of gravity of the disc and the oblique seat makes the valve close fast and reduces the risk of pressure shocks.
  • The design of the valve allows it to be fully open at very low flow velocity. (down to 0,6m/s)
  • Low pressure drop.
  • Short face-to-face suitable for all flange standards.
  • The valve is available in carbon steel and stainless steel.
  • DN 40-1000, PN 25–40
