Application:
These valves are used for lines where the fluid velocity is low and in pipe lines with shocking or quick return flow are not suitable option and spring-loaded check valves should be used.
- Very low turbulence in the flow
- Low pressure loss.
- Installation in all Positions( in vertical position ,the fluid should flow from downstream to upstream in order that gravity force will help to close the disc)
- Flanges :according to DIN EN 1092-2 (DIN 2501)
- Face to Face: according to DIN EN 558-1 Series 48 (DIN 3202-F6)
- Final test: according to DIN 12266-1
Corrosion Protection:
Electrostatic epoxy powder Coating with Min thickness 250 and certified by reputable international institutions for potable water.
