Axial disc check valve – Series B6 40

Axial check valve assisted with a spring

The axial disc check valve is an economical and robust solution to protect pumps against flow inversion.
This type of non-return valve offers good dynamic behaviour (low inertia and closing stroke, reduced pressure losses).
Compact, it can be installed in any position.

Applications :

  • Pumping stations for water distribution and irrigation (filtered water)
  • Drinking water networks and irrigation networks (filtered water)
  • Fire protection networks

Product benefits :

  • Hydraulically profiled disc optimising the passing of the flow.
  • Better translation of the obturator by fitting a bronze ring to limit premature wear.
  • Simple axial guidance prevents the valve from jamming.
  • Cable channel for submersible pump.
  • Stainless steel spring allows installation in any position.
  • Quick closure: anticipated closing to limit water hammer thanks to the standard stainless steel spring.
  • Long back axial guiding for reduced displacement (low inertia).
  • Minimum head loss.

Range :

  • DN 50 - DN 250
  • PFA 10 or 16

Technical data :

  • Flange drilling ISO PN according to PFA (standards EN 1092-2 and ISO 7005-2)
  • Working temperature : +10°C to + 50°C.
  • Seat tightness : Class A according to standard NF EN 12266-1.
  • Tightness from a pressure differential of 2mCE.

Norms and certifications :

  • ACS
  • WRAS components

Alternatives and options :

  • Lateral body bosses can be drilled on request for the mounting of manometers or by-pass
  • Drain cap 1/4“ in bronze
  • Drain plug 1/4“ in bronze
