Plate check valves – 815 pumping, water distribution, general industry
The 815 non-return valve is watertightness ensured by the spring which pushes against the two plates, maintaining pressure on the valve seat seal,
- Operating position : horizontal and vertical
- Minimum occupation of space
- Vary low head loss
- For pumping, water supply, general industry
- Closing system : double plate with return spring
- Sealing : metal on elastomere seat
- Using these check valve on networks equipped with piston pumps or compressors is not recommended.
