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.
